Sony Pictures Home Entertainment will be releasing two more entries in its Toho Godzilla Collection this September and, as an added bonus (for the dozen or so people that enjoy them, kaiju completists, or mere gluttons for punishment), all three installments of the late 90s Rebirth of Mothra trilogy.

Godzilla 2000, GMK/GxMG double feature, and the Rebirth of Mothra trilogy will arrive on Blu-ray September 9th. All will be digitally remastered in High Definition and English and Japanese audio options. 

Update: Godzilla 2000 will include both the Japanese release as well as the US release versions. All are two disc sets priced at around $20 they can be pre ordered from Amazon for $13.99.

We posted this in the past now they are showing up as pre-orders on a number of sites, all Godzilla 60th anniversary Blu-ray & DVD releases (all of the 29 titles including the '98 American Godzilla film) will be available. 

16 titles are newly released as Blu-ray format, and other 13 ones are reissued. They are listed close to $50 US but should be had for less, these show in listings on CD Japan as being region free, if so then for possible the first time US buyers can get the highly sort after Godzilla 1984 in these formats. 

Most include bonus material, trailers, making of, poster art, etc.
