My friend and I had some intense discussions with Chris over the course of the weekend. We were cautious before, but we're both pretty sold now after hearing the way the team has been thinking about the game. I'd say the thing that stood out to me was simply the dedication of the team to making the game we're all looking forward to.
I noticed a recurring theme watching (and reading) - the staff were as enthusiastic about the game as the fans that were there to see it. I think it's awesome and really holds true to those olden MMO core values of community and raw fun gameplay. Seeing how it unfolded at PAX only bolstered my excitement and commitment for the game.
