The only QTE in the combat are the executions. Otherwise is plays like a mix between Assassin's Creed and the Batman but with a focus on blocking rather than dodging and countering. For an example of this http://www.twitch.tv/microsoftstudios/b/477303820 here is a 50 minute live stream with lots of combat. If you don't want to watch the whole thing, skip to around 12 minutes. It's clearly not a QTE fest, so why are so many people still claiming this?
Now I'm sure people will cite things like the gameinformer preview about dialing numbers. But the thing they conveniently left out of their preview was they were playing an early part of the game with a fully upgraded end game character with everything unlocked. So of course it was easy and just pressing buttons.
The newest combat trailer itself also shows that the only QTE are the executions which I don't really mind. At least my fingers are doing something rather than every execution just being an automated animation.
I'm not claiming the combat will be good, that remains to be seen, but there is so much misinformation about this game it explodes my brain. Even if the combat does turn out to be not great, it doesn't look nearly as bad as people are making it out to be, and it sure as hell is nothing at all like what people are claiming it is.
