Rob Pardo, A Blizzard developer normally on Team 1 at Blizzard South, has moved to Team 2 temporarily to help with WoW now that TFT is done. He has been posting a bit today on the WoW Battle.net Forums and mentioned the above and several other things while he was posting. Among those was that they are currently working on getting all of the main game features in and the beta is "several months" away. You can check out his posts on this thread about whether any of the ideas that are posted on the forums get through to the developers and this thread which is simply another thread about the lack of WoW updates lately.
It is likely now that TFT has been completed that more and more of the Blizzard developers who were working on it will be temporarily shifted to Team 2 to help out with WoW since the projects are closely linked. However, they will be moved back to Team 1 as soon as their next project is underway.
