GoW 5 should be coming to PS4, and I could see it managing that coveted 95 this just missed. There's no need for a long dev cycle now that all the foundation has been laid, especially if you keep it on PS4. That should allow for a brisk 2 year gap between the two and hopefully a first half of 2020 release. Otherwise we will probably have to wait 3-4 years while the devs get the hang of PS5, and even then it probably won't live up to the potential it could if they waited until further into the system's life cycle to debut the franchise. GoW 5 on PS4 in q2 2020 and GoW6 on PS5 in q1/q2 2023 sounds like a good plan to me.
