While nothing is set in stone -yet-, it is extremely likely the show will be held in Santa Clara in 2010 at roughly the same time of year. We've had a very good experience dealing with the Hyatt Regency, and we think they will want us back!
Prior to this year, the show was in San Jose, so it hasn't moved far. We're unlikely to move again anytime soon.
Sorry to be so vague and thanks for your interest!
