The funny thing is that the player base on Switch + X1 + PC is still smaller than on PS4 alone.
Plus we still don't know everything about this new Microsoft/Switch/PC cross-play stuff. There's always the possibility of Microsoft simply not wanting to co-operate with Sony but with Nintendo to generate an advantage for their platforms. I'm not yet blaming Sony, I'll wait a little until we know more about what's going on. Someone should leak something sooner or later.
