and he might be. but with most places not even giving sources as to where said rumor came from, it is hard to tell how valid it is. and with games it is really easy for fan speculation to morph into a "confirmed rumor". look at how people though that the indian head test pattern being used meant it had to be a New Vegas related product.. when New Vegas didn't use that test pattern at all (that particular pattern, in B&W, was a fallout 3 thing)
a couple fans speculated groundlessly on a board somewhere, said speculation got mentioned in discussion on twitter without the speculation context, and suddenly everyone 'knew' it was going to be new vegas remastered or new vegas 2..
(i'm actually seeing a lot of the same for S.T.A.L.K.E.R. 2., with a lot of discussion of mechanics and story and what not, including hate filled rants over "the changes".. and literally all that has been announced is the name and the release year.)
