Based on the little bits we've heard, I don't think there is any evidence to that. I think that just about every change is an effort to just make a better game and fix some old systems that didn't work well. "Recommended potions" is the only thing I can think of that falls into the category you are talking about, and it's such a minor thing that you may have the option to turn off.
Well, I think the auto-refill potions problem is still a real problem.
Also, the Witcher sense needs toning down.
Anyway, the combat problem seems resolved since it has been pretty much confirmed that this was only for presentation purposes...
