But you really really don't want a wii u situation. If PS4 all of a sudden starts losing steam, PS5 can't still be 2 years out.I doubt it because this year will likely be fudgy massive for PS4 again. And next year has TLOU 2 and Death Stranding hopefully. 2020 seems the most plausible. 2019 would be a huge surprise to me.
I hope PS5 is years away but I wouldn't be surprised if it's 2019 either.
