I don't think it is fair to compare the PS3 situation with the PS4. PS3 had a lot of problems due to its unusual CBE which put many developers off. However, some games did run at 1080p/60fps on PS3 so in a way they deliverd what they promised, partially. PS4 pro is not meant to be a true upgrade, it's basically a PS4 that is capable of playing PS4 games at 4k resolution so it's not meant to replace the standard PS4, it's meant to be an option for new comers who own 4k TVs. They said from the day they released PS4 pro that there won't be any games exclusive to the pro version. I own a standard PS4 and I'm very happy with it and to be honest I don't see the need to get a PS4 pro. Bottom line, I don't think they rushed the PS4 pro nor they made a mistake by releasing it before the Scorpio.
The only major annoyance to me is when they decided to remove the optical port from PS4 slim, now that is outrageous.
