I don't see how it could be good. They just started pushing the pro and slim models. They'd essentially be -blam!-ing over anybody who bought one of those, not a good move IMO. Personally I think We'll hear about it at PSX in December with a launch date in late 2019. Unless the Scorpio starts to absolutely crush the ps4 then maybe they'll push it out sooner. But ps4 overall is still selling really well, even if the pro isn't selling quite as well as they'd hoped, so I don't see any reason to push out the next gen yet.
