That was a good panel. Quite a variety of backgrounds and points of view with developers of Wildstar, Guild Wars 2, Neverwinter, EverQuest, Star Citizen, and Elder Scrolls.
I especially liked the question about if MMOs should ever be shut down, specifically referring to City of Heroes, and the guy from EverQuest was emphatic about how that should never have happened. It was hard to tell exactly what Jack said after that, but it sounded something like having NCsoft pick up the phone and call him to get CoH back. I'm not sure how serious he was about that comment (most likely was just ear candy chit-chat for the people in the room), but he did seem to slouch a lot during the panel, almost like he wasn't terribly excited about being there.
I also thought it was interesting that EVE Online never got mentioned in passing about being a long-running sandbox MMO.
