Macromedia Labs gone online today.
“This download will install Flex Builder 2, the Flex Framework 2, Flex samples, command line tools, and Flash Player 8.5 for Windows. It also contains a .dmg file that you can copy to your Mac in order to install Flash Player 8.5 for Mac. There is an option to only install the framework, samples, and command line tools.”
I am still downloading and very curious!
