OS6 Software Bundles for 9700?

Hello, I am a Blackberry Enterprise Server Administrator.

I can go to the AT&T Software Download site and see that the 9700 has a supported version of OS 6.x available. So I could download it and via Desktop Manager, and start upgrading user's devices manually, but I have hundreds of users.

However if I want to push the software package out to users via the BES, when I search for software bundles via the BES, only packages to upgrade from some version of OS 5 to another version of OS 5 are listed.

example

5.0.0.405 (Platform 5.1.0.112) <- 5.0.0.296 (Platform 5.1.0.83) 9700  
5.0.0.602 (Platform 5.1.0.112) <- 5.0.0.296 (Platform 5.1.0.83) 9700   
5.0.0.602 (Platform 5.1.0.112) <- 5.0.0.405 (Platform 5.1.0.112) 9700  
5.0.0.979 (Platform 5.1.0.177) <- 5.0.0.296 (Platform 5.1.0.83) 9700   
5.0.0.979 (Platform 5.1.0.177) <- 5.0.0.405 (Platform 5.1.0.112) 9700   
5.0.0.979 (Platform 5.1.0.177) <- 5.0.0.602 (Platform 5.1.0.112) 9700

Is there an ETA for when a 5.0.0.979 to 6.0.0.526 bundle might be published?

Thanks
