If you haven't heard by now, Garage Games has cancelled IGC this year. (See http://www.garagegames.com/blogs/55/11132). What a bummer; I was really looking forward to going this year, especially since I'm using TGB now. Not sure if there were other reasons why they cancelled it, like Jay Moore leaving, or if they lost some attendees to other conferences (like Casuality and the Casual Games Conference). Hopefully they can resurrect it for next year.
