I´m still on my first playthrough, and have a lot left to see in Dark Souls, but at the same time I just don´t want it to end, so anything that can add on to the experience is great. What I like most about it, with the information we got now, is that there will be new areas to explore. If it had simply been new weapons/enemies/bosses set in old areas I wouldn´t have been as into it as I am now.
So what about you? What are you looking forward to the most?
