Unimaginative? You mean the opposite. Many people did expect a RS remake and Grey/Gray version, but instead of the same game with improved graphics and Kyurem instead of Reshiram/Zekrom, we instead got a direct sequel, something that has never happened before. And it was awesome. Also, genetics/DNA is the obvious theme, I mean, just look that the Japanese logos-Chello said:I highly doubt it, but its possible. I mean, most people were probably expecting Pokemon Grey or a Ruby/Sapphire remake. It may just be a coincidence, but I think Nintendo may have just become unimaginative
Also, since genetics them is the theme, I think that the DNA splicer (or at least a newer, modern, and improved version) from B2W2 will reappear, along with the Berserk Gene from Gen II as well, to go along with the theme. Maybe the DNA splicer and the berserk Gene (Mewtwo held it) will have something to do with Mewtant?
