Right now the only AKV units are the converted rooms in the main lodge. The new construction at Kidani Village won't open until May 2009. So if I had to guess, I would say we won't see anything in II until 2009 or maybe later.
We stayed in a AKV value studio on our DVC points last March and it was very nice - flat screen TV's, and even had a pool view (surprised - figured we'd be looking at a parking lot).
Here's some info on AKV over at allearsnet:
