hehe, since the launch of the Nintendo DS, most new games for it seem to come out on it, rather then the Gameboy advance... And wouldn't you know that after having got a Gameboy player with my Game Cube (back when I first got it), well...
As the guy above me had mentioned, probably after so many months, they'll be wanting people to upgrade. I only wish they'd come out with a DS player or something, as I most often play at home, rather then in the car or something. Probably could get the DS and some cable to link them though...
Probably after it's been around for a season or however long, game companies will just end up moving to the newer platform, and give their fare wells to the older. Not necessarily in a forte night though... Just so Revolution can still play Game Cube games, it shouldn't be too bad beyond money, and the Game Cube could be traded in. Given one first got it for $99, and it's seen a price cut already, not sure one would get much in trade in value however...
