No we won't. By any rational person's deduction it is already a failure, one year is not going to change that. It has carved out it's own little niche in JP and will not break Gamecube numbers worldwide. People will keep denying Vitas failings until it's actually pulled from the shelves. The same goes for Wii U, though I personally would excercise some caution when talking about a console which has yet to recieve it's biggest games. No doubt it'll never be "a success" but it could move enough units to be a gamecube 2.0.
If only...
