Definitely! I'm sure there will be a lot more information appearing on the forums, particularly when we start organizing events, but from talking to people and extrapolating, I'd estimate there are at least 30 or 35 who already have tickets and/or lodging.
Last year we even had DayKnights join us who weren't attending TwitchCon, but were in the Bay Area. With the event in San Diego this year, we definitely want to hear from all of you down south!
The first TwitchCon was a great time, and we hope to make our little part of this one bigger and better!
