X-Plus will be releasing a limited Winter Wonder Festival Exclusive Godzilla '54 Train Biter Electric Train Color Version, this is the Natural color version revealed back in Dec with the train being a reddish color instead of the brown, otherwise it appears to be the same figure. It's 34cm tall and 42cm in length, and will retail for 23,000 yen (it is actual slightly less expensive than the natural color version). It will most likely be limited to Wonder Festival. Winter Wonder Festival is Feb 19, 2017 at Makuhari Messe International Exhibition Hall.
