We don't offer any formal tournaments at ConnCon. I've heard rumors that people may be offering unofficial ones that would be organized and set-up on site, but we'll have to see what comes of that.
Preregistration is indeed live! I might suggest to some that they hold off a day or two if they are interested in Steve Jackson Games ... our event submissions from the "Men in Black" came in just past the deadline and missed the website launch ... I'm going to see if we can get it added asap. Otherwise all Steve Jackson games will marshal on-site.
