I haven't received any more word on the 1/22/2010 update. I would think that phones running the Sense UI or simmilar overlay may be late on the update while updates are made for that as well. But, Google, HTC, Verizion, etc. may be ahead of the game and get it pushed out all on the same day as phones that run the Android base alone. I have a Moto Droid and haven't gotten the udpate yet.
