EA would be a bigger surprise.
I won't argue, but I think it's not the time yet.
Anyway, after EA coming on board, there will be noone who would refuse GOG, so I have nothing against it.
I'm honestly expecting either Square enix (eidos titles) or Bethesda
Square enix is highly possible too.
Bethesda, with all respect, doesn't have that many great titles. SLP2000:
I'd be shocked.
That would mean that GOG stops being "Old", and probably that there will be new price point.
Although that (exclusive sale) would bring gog zillions of new users
perhaps you weren't aware but...the company now owns the publishing rights to ID's software titles
if bethesda goes on board we will not only get morrowind but also Doom and Quake
