I very rarely do a new game + straight after finishing a game , I like to revisit it after a while (only problem with that is you can forget the controls lol)you aren't playing NG+ on launch.
it is very chunky actually. 20h-25h on easy is huge game for linear experience.
i am pretty sure, there is going to be difficulty spike down the road. so people will have to learn how to use parry, dodge etc..
