There is absolutely 0 chance Sony gets a 12 month exclusive. Even 3 months is not gonna happen. The most that's going to happen is marketing rights and maybe like a week of early access/beta, or some in game stuffI wouldn't be surprised if Sony locked it as a PS5 exclusive for 12 months.
PC development is a no go at launch, the green base won't buy games, 2 SKUs development over there.
Jim Ryan last surprise before he left.
How much it would cost, probably 100-150M.
Also Sony didn't project 25M next year to for no reason
