I doubt this game will go to any other platform, but the sequels would i'm sure. People though Colors would go to different platforms and it didn't, people thought Generations would hit U and it didn't. Even when not under contract Sega seems to ignore money, so with an actual deal at hand I doubt they will be going anywhere.
I think there was an article somewhere that said this was the third and final game in Nintendo's exclusivity contract with Sega for Sonic games. So you're probably right; this game will stay on the Wii U.
If there's a Sonic Boom 2, though, that'll probably appear on everything.
