Globally, PSV is doing similar numbers to 2013. In 2013 it did around 1.5M between Oct-Dec. Based on that I'd say it has a chance to reach 10M by end of the year so I pick Vita as hitting 10M first.
Another way to look at it is estimate that half of yearly sales are the holidays, so estimates by end of the year:
1st PSV 1.51 * 2 + 7.36 =10.38M
2nd Wii U 1.84 * 2 + 5.42 = 9.10M
3rd XB1 2.44 * 2 + 3.06 = 7.94M
