PAX withouth Penny Arcade? (C2E2 in Chicago)
Seems like that's what Reed Exhibitions is trying to accomplish with their C2E2 con, or at least inject a little PAX flavor into it:http://www.mediumatlarge.net/2011/02/gaming-at-c2e2.html
For a comic-con, it sure as hell doesn't sound like NYCC, which they also run. I think the strategy here is to give a PAX-like event for those midwesterners who can't make it to the coast, and why wouldn't you adopt that strategy? PAXes sell out like hotcakes.
