I have been monitoring this site for the last 5 months waiting patiently for Gumbo to try it out. I now have the Adobe CS4 package and would like to try doing some of the things that Lee Brimelow has been showing in his tutorials with Flex and Flash. Is Gumbo going to be available for beta or are you just going to by pass that stage and only offer it for sale? I am sure that I am not alone in the fact patience starting to dwindle.
There will be a beta and it's scheduled for June. You can except to see it sooner rather than later. Thanks for hanging in there.
It's available now!
You can download betas for Flash Builder 4 (formerly Flex Builder) and Flash Catalyst (formerly Thermo) from http://labs.adobe.com/.
Nightly/Milestone Flex 4 SDK builds can downloaded from http://opensource.adobe.com/wiki/display/flexsdk/Download+Flex+4.
