I just played through on Normal to get it done somewhat quickly. Took me 5:56! What about you guys?
6 hours on heroic
6 hours just about
4 hours 20 mins on Normal.
1 Day 2hrs 16 minutes to complete everything. Maybe like 9 hours for my first run through on co-op with my friend. We were wandering around a bit though and not rushing.
6 hours 34 minutes, heroic solo. And that was with exploring and taking my time.

Took me around 7 to 8 hours on Heroic. I took my time and enjoyed the sights.
One day, on Heroic.
7 hours on Normal and I dilly dallied a lot too, so I was a little disappointed in its lack of length. But it was fun.
13 hours legendary co-op
