I think i saw some prediction where someone predicted that the DS would get a noticeable bump, maybe even selling more than the Vita. Seeing the DS hardware numbers, i wonder if this is old stock and that Nintendo have completely stopped shipping out more DS hardware.
Well the 3DS apps were made to encourage 3DS sales. But it seems most people are content to play on whichever DS system they already own. Or they are waiting for the 3DS LL. Anyway, it's a bit surprising to me that 3DS received such a small bump.
