The only new internet rumor that is currently making rounds is from korean source which pegs the prime launch for october. Original roadmap had this mystery ICS device for december launch.
This is suppose to be the ice cream sandwich launch device and we have absolutely zilch about this version of android.
We usually have something of next android launch few months before it actually go official. The only thing we had turned out to be fake images.
Not to mention we do not know kiowa the new motorola acquisition will impact the whole scene. (it won't cause any big changes for now, but we may get few surprises).
Google has nothing to worry about iPhone 5. And they usually do not like to have their launch conflict with major Apple launch. If iPhone 5 is just small increment, they can let the ice cream sandwhich powered superphones loose immediately. If not, they have enough time to catch holiday/ new year shopping rush with improved formula.
Traditionally google android big launches have been december with good retail availability in jan.

EDIT: The one logical reason to pull the launch ahead will be to counter possibility of another lawsuit by Apple by unavailing the Prime before iPhone 5
But I would be very surprised if they manage to pull out the global launch this soon considering the specs of the device.
