HaloFest Contests! Will they use TU settings?

IGN just announced the HaloFest tournament scheduling for the 3 days of HaloFest.
Detailed here http://xbox360.ign.com/articles/118/1187658p1.html

My question the the community and to 343i is, will these “Anniversary” contests be using the new TU settings? And is this how the players attending HaloFest are going to get hands on with the new maps and TU gameplay tweaks/settings?
