Well fuck me, I hadn't figured. I can only assume you didn't read any of my other posts.
Although, I do think Nintendo could get away with things that Sony can't because Nintendo have literally every single 'big' handheld franchise locked down. If they made the Vita, it would've sold just as well as the 3DS. If Sony made the 3DS, it would've bombed like the Vita. You just can't fuck with Animal Crossing, Pokemon, Monster Hunter, Dragon Quest, Mario Kart, blah blah blah. Sadly, I have no interest in any of those but fuck me they don't half shift units.
For me, the perfect handheld would have Sony hardware and Nintendo software. In this fantasy, third parties jump on board with both feet.
