If you are not enjoying your PS3 or there is not much ahead that you don't want for it then go for it. I really can't help you with that part since only you know. But with the other part each have there strengths. DS has way to many RPGs while the Wii has Nintendo games and diffrent kinds of games (ex:NMH, De blob and Okami). Depends on your tastes...
