Well, considering SEGA is limiting most of the supporting cast's appearances in the mainstream games, Silver returning in a main series game would be rare.

Of course, the problem with Silver coming back is why he's returning. His future has been restored, as said in the DS version of Sonic Colors, so his role in the universe is pretty much finished.
