Meh... I think he is saying the Xbox 360 and the PS3 are too complicated for DEVELOPERS and have no big fan base to make it worth his while to learn it.

Meanwhile the DS is cheap, has lots of fans and is realtively easy to develop for. Great short term strategy.

A pity he is just thinking short term though. pretty soon the DS will be obsolete / tapped out and he will have a big learning curve ahead of him
