I never really understood why the two were supposed to be mutually exclusive. Especially since so far, PoGo isn't all that social. Sure, we had that summer last year when everyone was out playing, but these days it's mostly just a handful of people in my city, each doing their own thing. There's no trading, no direct pvp, no events to cooperate on, despite what was shown in the original trailer. The core games are more social than that.
So yeah, I hope they can do both, add social functions, and functions that are reminiscent of the original games.
