Asus UK have taken to their Facebook page to let us all know the state of their Ice Cream Sandwich update for the original Transformer. To cut a long story short, it's good news. 

They're confirming the update is incoming, although exact date is still TBC. What they have said is that they're working hard on getting the OTA update out as soon as possible after the Jan. 12 launch with the Transformer Prime
