About the only thing that does scare me about Perl 6 is the (very slim) chance that we might not get it finished. It's just so much more fun programming in Perl 6, even if it's still mainly in my head. I'd hate to see us ever have to give up on it, and let the naysayers and FUD-mongers win.
Larry and the rest of us are all still totally committed to the project, of course, but we definitely need the economy to start picking up soon. As Larry mentioned at the end of Apocalypse 6, our day jobs are beginning to interfere with our Real Work. :-(
