The timing is very interesting because Java EE 6 is now really getting a lot of traction (don't miss the sessions of the Java EE day) and the final Seam 3.0 is about to be released. I will be able to demonstrate some nice new stuff with Flex, GraniteDS and Seam 3.
I'm also happy to speak just after the keynote of Michaël Chaize from Adobe who will certainly show lots of awesome Flash & Flex demos on various mobile platforms.
If I can find enough time, I'll try to also do a short demonstration of a multiscreen Flex/AIR application on an Android phone.

See you there !
