Despite what people say about the kanto starters and mewtwo being available in X/Y, I hardly think that writes off Kanto remakes on the 3DS. With the release of OR/AS, Kanto is now the only region without a game on a DS or later system (HG/SS Kanto doesn't count, it's barely an afterthought in the game), plus FR/LG are now more than 10 years old. I fully expect another Kanto remake before we see a Gen 4 remake. I expect to see a Kanto remake on the 3DS or new 3DS, or better yet an entirely new game based in the Kanto region. 2016 is the 20-year anniversary of the release of Red and Green in Japan, and 2018 is the 20th anniversary of the release of Yellow. To me, those are the two most likely times to see the remakes released: 2016 gives GF a year to make X/Y sequels OR a release an entirely new game, and 2018 allows for the potential of a new console depending on Nintendo's plans (though I admit in this case a Gen 4 remake becomes much more plausible than it is now).
