Comic Book Resources has a great articles where they ask some of the comic book company execs that were there for C2E2 their thoughts on the event, and for the most part in my opinion many of them were spot on in their judgment, and very, very honest. The potential for the show in the future is huge, especially if companies and fans keep throwing support behind it. I loved the venue they chose to host it, it was supported by a ton of my favorite companies and my favorite groups, and they really catered to everyone having a good time. There were a ton of a panels (actually, maybe a few too many from the vendor viewpoint that kept many people off the floor most of the weekend) and the guest list was impressive.
C2E2 really has a chance to be something great in a few short years, and I for one will be pushing it hard and I hope other fans and companies do as well!
