Apple updates in the pipeline

OS X and iOS could be updated Friday?
From the whispers we are hearing, the updates are necessary for the support of AirPrint and AirPlay streaming functionality that is said to be in the pipeline. Of course, to take advantage of this functionality you will need iTunes 10.1, which is also expected to arrive at the same time.
A number of other sources around the Web seem skeptical about a Friday release yet seem to be in agreement that the updates are in the pipeline. Based on what we are hearing, we, too, would have to agree.
