I wouldn't blame anyone for waiting until more games come out. The only reason I didn't wait was because all the stupid salesmen I talked to all said basically, get it now or you might not get one until after Christmas. Mixed with the earthquake in Japan I was worried about supply issues. Meanwhile you can't walk through a game store without tripping over the things they have so many left.
I don't know if its even possible but it would be really cool if they could come up with a software solution to convert regular DS games into 3D.
