[flexcoders] About Flex 4 release time

[ivan.wang2010]

Hi, all
   I'm about to start a new project, and I've no idea whether to choose flex 4 
or flex 3. Although Flex 4 has a great advantage over the previous one, but I 
can't rely on a beta version to make the product.
   So does any one know the official release time of Flex 4? If it is quite 
close, I will take Flex4. After all, the new skin and effect is very 
interesting.
