Godzilla sequel

for those who remember a long time ago there was a mention in 2013 that a godzilla sequel is in the works. from what i gathered these are the things that might be in the sequel (if the sequel exists): 1. it would have hedorah and his (or her i don't know really)origin would be from a nuclear power plant accident 2. it would have a new monster called mitodah or something that would be an "earth saving monster" 3.it would have a destroy all monsters like thing going on (maybe there's gonna be aliens i don't know) 4. it would have a monster island setting
