I assure you, if Sony put together an exclusive lineup of that quality, variety and quantity, PS fans would be ecstatic. There's no question about it.
I thought for sure Death stranding would've been a PS5 game, but then again the game looks meh TBH. My prediction regarding the first year is Ghost of Tsushima, TLOU2 and maybe the next Horizon game will be PS5 showcase games. Xbox Two showcase games will be Halo 5, Forza 7 and Possibly Fable 4 from playground games.
