Is the Gamecube the new Dreamcast? No exclusives left, useless console in 2015?

Not realy. Eventually all games will end up on modern hardware, just because there is a demand for older games, both from people that want to play them again and from people that never got them. Retro gaming is harder and harder every day, because the games just become harder and harder to find.

Also, by that argument, full backwards compatibility made the GameCube useless the moment the Wii (and Dolphin emulator for that matter) was released.
