On the one hand, this is making me think that's the case.They have 5 major announced games already .days gone, dreams, ghost, death stranding and TLoU.
Maybe theyll announce something in the next 6 months releasing early2020. Show off PS5 in early 2020, and release it in the fall with big titles.
I don't see how they will release a PS5 in 2019. Days gone is the early 2019 game, dreams is 2019. No doubt that at least two games from TLou, DS and Ghost are releasing in 2020.
Or the new unannounced game could be from Sony Japan, something like gravity rush or TLG.
