XCOM moved nearly twice the units on PS3 & 360 as it did on PC, so unless XCOM 2 is rotten with F2P mechanics (which is an easier sell on PC & mobile), I would be shocked if this sequel doesn't make its way to current gen consoles eventually. If they are leaning super hard into providing a robust toolkit for modders though, it would make sense that resources are thrown at PC/Mac first, and then a leaner version for consoles later.
Gee those numbers seem suspiciously similar to ones from a certain banned site.
