Why would ANYONE want BO:Declassified to sell well?! It's one of the worst games of all time, so every single person who buys it will be pissed off and will probably resent their Vita for being home to such a dismal game.
OT: I have no idea. Does it really matter anyway?
My prediction threads:
Wii U will sell under 40m units (made on 14th September 2012)
PS Vita will sell under 20m units (made on 30th September 2012)
Wii U will sell under 7m in 2013 - I was right
