I'm pretty sure this is the last Pokemon game for the DS, sadly as I don't think Pokemon can pull off 3D well. (the 3dPMD looks... "chunky" and not as good as the older ones imo).
Weren't people thinking this when there was a switch from the Gameboys to the DS? If you don't buy this system, you can't play, ever again? All systems are put out eventually, I guess it's the DS's time. =/
