While the idea is nice, especially since one could utilize the Wiimote as a DS stylus. Maybe in the far future they may implement some kind of GBA Player for the Wii since the DSi cannot play GB/GBA titles. But more than likely they won't jump on the idea since the DS already play most GB/GBA games and it still sells strong IIRC.
I would love to see a DS Player, but I dunno how good that would do. But I already own a Wii, DS, and a GameCube with a GBA Player. So I have all of my bases covered.
