Congrats to the PlayStation Vita, but it is on its last legs. I don't see 20 million being even remotely possibly since hardware manufacturing is almost over. It's interesting that the Vita is kind of an inverse of the Wii U. The Wii U did best in NA and tanked harder everywhere else, while the Vita tanked hard in NA and did way better everywhere else. Plus both have the cross-play aspect in different ways.
