I'm sick of this crap. Vita is going to do quite well for itself, it will likely make a profit, and will sell approximately as much as the PSP. For Sony to go up against Nintendo twice, where no other company has ever managed to do it once is amazing.
Why must we delude ourselves into thinking Vita has a chance of winning? It will only lead to disappointment when it fails to happen, and believe me, Vita will not have disappointing sales.
