For the first number they targeted:
62.5% (10 million) for Vita and 37.5% (6 million) for PSP.
Doing the same for 12 million you get
Vita: 7.5 million and PSP: 4.5 million
But that's for fiscal year (march 2012/march 2013), meaning no launch sales. There's simply 0 chances right now of reaching that second target. For both.
