Here are the Talks page http://www.gtac.biz/talks which ironically page crashes Chrome since it tries to load up a very large number of video players :)
The agenda is quite impressive http://www.gtac.biz/agenda and although there is only one security focused presentation ('How Hackers See Bugs' by Hugh Thompson) I bet security is covered by other presentations.
Look for example how there is no OWASP references (including I believe) project leaders. If OWASP wants to change application security, this is the one of the places to be. That said, not all is lost, since I just noticed that Hugh Thompson did a presentation at OWASP MSP in March (http://hughthompsonowaspmsp.eventbrite.com , videos not online)
