Unfortunately that's not the way the software development cycle works.

If you read Ageil's report he states quite specifically that the version of 6 running at Siggraph is a beta.  It's there to generate interest & publicity, and to give users, investors, competitors, and all those with an interest an idea of what the finished product will contain.

And it certainly looks impressive!
