Probably not. Techfest is Microsoft Research's day in the sun. They'll be showing things like illumiroom, and parametric speaker arrays, and virtual interactions with a desktop and lots of other things that may or may not one day become part of a product, but they won't show an in-development product that they're trying to maintain secrecy about. Not even to FTEs.
My favourite techfest talk was a guy showing how moore's law has been broken now for 5 years, and dark silicon will essentially force us into more fixed function hardware to improve performance, as opposed to just throwing more transistors and clock cycles at the problem.
