i don't think it's 2013 or bust, the lesson of MH is one must have game can really turn things around. the lessons of the wii is that generations are now able to turn on a dime.
but with that said, vita is in a bad positions. i am quite certain that only sony can turn this around as i can't see any third party taking the required risks. putting ps+ on vita seemed to help at least among my friends of previous psp owners. ps4 interaction could be interesting. but really, it needs big games. it's doing good, imo, on the small games front. but it needs a system seller. right now i can only see two potential system sellers. soul sacrifice for japan. tearaway for the west. ..but if vita's last hopes ... things probably won't end well.
here's hoping sony has something to announce for next year. if not, well, i don't want to think about that right now.
