It looks like Asus stealthily started rolling out a new update for the TF700 Transformer Pad Infinity today. The update is version number [10.4.4.23], and several of our members have reported receiving it. One of our members over on TransformerForums was one of the first ones to report it.
You can find his thread here: New TF700 firmware [10.4.4.23] rolling out this morning 12/10/12
Thanks for the tip, osmosis!
