Sony is not going to let the vita die, it will pickup... it will have a good showing at gamescom... wait and see
People have been waiting for a good showing at any of the major shows (E3, Gamescom, TGS) since E3 2011.
What I don't get is that people are justifying the PS4 focus by saying it's a new console and needs all the push it can get... well, then that's fine; but then when is the Vita focus going to happen since it didn't come at Gamescom 2011, TGS 2011, E3 2012, Gamescom 2012, TGS 2012, and E3 2013. Even the Vita Heaven event in 2012 was abandoned in Japan and pushed to 2013 largely to announce a F2P game and a price drop.
But, yeah... 'wait and see'...
