I have a feeling we're going to see similar results between PS4 pro and Scorpio comparisons compared to PS4 and Xbox One comparisons, with games running at 4k.
40% performance advantage has definitely helped PS4, especially with exclusives, but I give developers a lot of credit for getting the Xbox One versions of games up to par with PS4 for the most part.
But I fully expect, PS4 Pro checkerboard games will look very, very similar to Scorpio games running at native 4k. And then you take into account that the vast majority of consumers will be making their comparison decisions based off of IGN comparisons videos from YouTube.
I don't think Scorpio isn't going to be a driver of gamers back to Xbox, even if that is the goal of the console or not. I have a feeling that all of this speculation is going to disappoint a lot of people. If you are already into 4k and a console gamer, you'll be happy to have your games looking pretty on a nice new TV. For everyone else, it's probably not going to blow your mind.
