If Sony and Ericsson's partnership didn't end so soon, they might have been able to make the Vita as a full-fledged gaming smartphone, kinda like how the Xperia Play does for the PSP. that would have been so much win, a smart phone with actual game buttons and dual analogs with monster specs.
also, they should start bundling their TVs with PS3s (or the other way around). this should help their ridiculously expensive TVs into actually churning out some sales. hell, they should release a TV with BUILT-IN PS2/PS3 capabilities. no other company has done that, nor thought of it. only Sony is currently in a position to actually try something crazy like that, and crazy might just be what they need. that could be their new Walkman. sure, it'd be expensive, but hey, built-in PS3? so much win.
