2020 The PS4 is doing Terrific, there is no need to release PS5 yet. Considering TLOU2 most probably will release in 2019, I dont think they would announce PS5 and steal the thunder of the game
It's not as if PS4 stole tlou thunder in 2013 anyways, and now it's even less likely now that it's a renowned game/ip and not a brand-new one.
Not that I disagree with you that's it's coming in 2020 anyways.
Bet with Intrinsic:
The Switch will outsell 3DS (based on VGchartz numbers), according to me, while Intrinsic thinks the opposite will hold true. One month avatar control for the loser's avatar.
