My original PS4 is still running fine and not causing any issues, it just gets a bit less time now considering I got gifted a PS4PRO when it released.

It also really depends on the dev studios to step up to the plate but I think a start with Spiderman, Horizon and a GT game within the space of two months should be a good start.
