Its True! Beta 3 is up on labs. Flex Builder is still a Windows only product, but all the other downloads ( SDK, Charting, FDS, and Flash 9) all have Mac OS Downloads.

Not only that, but the wonderful CF team have made a CF Mystic update for the Mac! Thanks to all the CF team for that wonderful suprise, because it means I dont have to spend the next hour trying to get it working so I can play with the Beta 3 SDK! :)
