Unless things improve i heavily doubt the 3DS will reach 90 million. It's sales have fallen off a cliff this year.
I do expect the WiiU/X1 will outsell it, but i'm not going to predict any numbers. The X1's future (and to a lesser extent the WiiU's) is still very hard to guess. There are an awful lot of variables that could sway things heavily one way or another right now, so any number i say would have been plucked from thin air :p
