I don't want to make any predictions really until I see how Japan takes it really. But I'm gonna be manly.
If it sells well enough in Japan over the Holidays, then I suppose there could be about 2.5 WW. Possibly more.
Not too bad considering what's released for it.
By the end of the year -
~ 1 Million in NA
~ 1.1 Million in EMEAA
~ 350k in Japan?
This is without even looking at what's releasing. And a quick guess from the top of my head.
