haven't decided -- quite possibly neither. overall i'm pretty happy with my iphone, not really an amazing gaming system but good enough and most importantly very convinent (read: portable) and functional.
i'm mostly sure i won't be getting a 3DS -- the one feature that may make me get a psp2/NGP is if i can take a ps3 game i'm playing and port it over to the NGP to keep playing on the road. somehow i'm not really expecting that though.
either way, if i do get either i'm not going to be an too early of an adaptor -- 2012 or bust!
