SNY and MS need to figure out how to sell more Pro units this gen, or don't bother at all and just reduce the pricing quicker and lifecycle back to 5 or 6 years. Selling more Pro units also may mean waiting 4 years this time instead of 3, for a huge clearly significant upgrade.
The thing to do this time around for a Pro console, would be to push as many (AAA) games as possible, to advance far enough, that the PS5/XBSX basically become a 1080p/1440p console and the Pro becomes the new 4k top tier. This would likely make many more gamers upgrade to the Pro models this time around.
