As you might already know Adobe hosted a Flex Community Summit in San Francisco early December this year. The recordings are now available at Adobe TV:
Flex Community Summit: December 2011
There is also a segment about Falcon and FalconJS that I recommend watching if you are interested in FalconJS:
Open Discussion about Falcon and FalconJS
Peter Flynn did a great job explaining FalconJS’s architecture and its current limitations in regards to cross-compiling Flex applications. I found interesting that the developers in the audience were eager to get the source code for FalconJS as soon as possible even though Adobe’s Flex team considers FalconJS for Flex an early research project.
