That's just plain silly. They didn't re-release all the great PS2 games on the 360 when it came out. Nor did they re-release all the great Nintendo 64 games on the Xbox. If you want to play those games, buy the damn console (or PC) that they were intended for.
Of course they didn't, because there was no need: PS2, XBox, and GCN were all in the same "league" of systems (essentially), so third parties usually made games for all systems. With 360, PS3, and Wii, however, Wii was in this "lower" tier of gaming, and TONS of third party titles never made it to the system. Also notice that when the Perfect Dark sequel came out for the 360, they rereleased the original N64 Perfect Dark for it. The same thing with Banjo Kazooie and Tooie when Nuts'n'Bolts came out on the 360. So this has happened before, and while I cant say for sure one way or the other whether this WILL happen again, there's no reason to dismiss the possibility.
