With Kong; Skull Island in theaters, and looking like it will do well thanks to the positive reviews, most will soon be turning their attention to the future MonsterVerse films, Godzilla: King Of The Monsters and Godzilla Vs. Kong.

The fact that the two films will be released within a year or so apart from each other lends to the possibility of the two being filmed back to back but it isn't only that. Most films in the same series have usually a break between them of two years at the minimum, take the current Star Wars trilogy which are each spaced two years apart (with the solo Star Wars films in between).

Another thing is the announcement today of a writing group to work on Godzilla Vs. Kong, consisting of Terry Rossio, Patrick McKay, J.D. Payne, Lindsey Beer, Cat Vasko, T.S. Nowlin, Jack Paglen, and J. Michael Straczynski. Godzilla: KOTM is only slightly ahead of this with writing being worked on and the director, and a few actors being named. It wouldn't surprise me to see this group help with rewrites that surely will happen with Godzilla: KOTM.

​It would completely make sense to do this and give a flow from one film to the next given they will most likely take place in the same time frame unlike Kong: Skull Island and the first Godzilla film. It could also ensure the actors in Godzilla: KOTM film return for the next film, something which may not happen with the Godzilla actors for Godzilla: KOTM. 

While this is pruly speculation only time will till if this ends up being true.

From Variety 
It was posted a while back that Michael Dougherty would write the Godzilla sequel with Zach Shields, now it has been announced he will direct it as well. He has apparently been working on writing it for a while and now was offered the director's chair. He has worked with Legendary before so he was known to them. Alex Garcia will oversee the project for Legendary. No word on Thomas Tull's involvement.
Godzilla 2 is currently dated for Mar. 22, 2019, with Godzilla vs. Kong set for May 29, 2020.

Warner Bros has announce that they updated some release dates for future films including Godzilla 2 (March 22, 2019) and Godzilla Vs King Kong (May 29, 2020). While this gives G Vs KK an official date, Godzilla 2's date is moved nearly 9 months, from original date of June 8, 2018.

The main reason for the move is Transformers 6 had the same release date (and the Jurassic World sequel being scheduled to be released two weeks later) but some may wonder why move it so far into the future. Other thing is 2018 is a pretty full year release wise, there are a number of major movie releases. 2019 is far less crowded and March will put it far enough away from the two biggest releases Avengers Infinity War Part 2 and Justice League Part 2 (May and June releases).

There is possibly other reasons that have not been said to explain the length of the shift. Pacific Rim was originally scheduled for March 2017, a little over a year before Godzilla 2 original release, it was moved to August 2017 when Kong: Skull Island was moved to March 2017. Pacific Rim has since been pulled from the calendar but with a recent announcement of director Steven S. DeKnight being added to it the possibility of Pacific Rim being added back to the calendar is likely it would not be placed in the vacated spot from Godzilla 2 so it may get a later 2018 date.

Another possibility is Monsterpocalypse, Warner Bros got the movie rights to this kaiju board game and it would need to be added as well to the calendar of releases. There could be other simpler reasons like a normal delay (because of director or actors involved) or just that they want the two Godzilla movies closer together. In any case fans just need to be patient and hope for a great film(s).

Press release
Following Legendary’s and Warner Bros. Pictures’ 2014 success with the global reinvention of the Godzilla franchise, the companies have come together to create an epic, new shared cinematic franchise. All-powerful monsters become towering heroes for a new generation, revealing a mythology that brings together Godzilla and Legendary’s King Kong in an ecosystem of other giant super-species, both classic and new. Monarch, the human organization that uncovered Godzilla in the 2014 film, will expand their mission across multiple releases.

The announcement that the reinvention of monsters continues was made today by Legendary CEO, Thomas Tull, and Kevin Tsujihara, Chairman and CEO, Warner Bros. The initial trio of films are 2017’s KONG: SKULL ISLAND; GODZILLA 2 in 2018; and then GODZILLA VS. KONG, arriving in theaters in 2020. While Legendary maintains its new home at Universal Pictures, the GODZILLA films remain in partnership with Warner Bros., who will now also distribute KONG as a part of this franchise. Production on KONG: SKULL ISLAND begins October 19th.

Warner Bros. and Legendary released Godzilla in May 2014 with an agreement to release Godzilla 2 on June 8, 2018. Both films feature the human Monarch organization. Shortly following Legendary's pact with NBC Universal, Legendary acquired rights to additional classic characters from Toho's Godzilla universe, including Rodan, Mothra, and King Ghidorah. This paved the way for developing a franchise centered around Monarch and anchored by Godzilla, King Kong, and other famous creatures.

When Legendary announced films centered on Godzilla and Kong, fans all over the world speculated these two characters might one day meet in the same film. Classic Toho monsters including King Ghidorah, Mothra, and Rodan, as announced at Comic-Con 2014, may also join the Legendary pantheon of giant monster mayhem going forward.

“Audiences really responded to Godzilla,” stated Tull. “Today, I’m excited to reveal that film was only the beginning of an epic new entertainment universe. As a lifelong fan of these characters, I’ve always wanted to see the ultimate showdown, and today we’re pleased to be announcing that and more.”

“Working with our partners at Legendary, we enjoyed tremendous creative and commercial success with `Godzilla,’” said Tsujihara. “It’s great to be able to revisit these characters and help create a franchise with so many creative possibilities for filmmakers. Fans love these big, globally iconic films and it doesn’t get any bigger than this.”
