If I had to guess, I would say no, the industry doesn't view them as a success but maybe not a failure either. I own both PS4 Pro and Xbox One X and can't say the upgrade was worth the asking price of each system but then again, both systems got me to upgrade my tv to a 4k HDR one so maybe that was one of Sony's and MS's goals (to push 4KTV's for next-gen consoles).
You see, a lot have said the midgen wasn`t worthy but still bought it, and it represents around 20% of the sales.
