Without reading the entire thread, I can see the benefit of NG+. Personally, I am a completionist, and would never finish a game while leaving side quests, etc out, so I might not use it in that respect (to do things I hadn't done before).
My initial thought as to the purpose of ng+ was to allow easier integration with future expansions and DLC geared towards post-game (and/or higher leveled) content. And actually, I'm still not clear on whether the 2 announced expansions will be meant for post game (main story) play or not.
