Solved! I asked this question in another Pentax forum, and this is what I found out: The kit lens in this bundle is actually the THIRD generation of the 18-55, which was released at the same time as the K7. So - an even better deal than I thought!
(Or so I suppose. Haven't seen a review of the new kit lens, but it is unlikely to be a downgrade from the last one, I'm sure!)
I had the same question - I thought it was a typo. It looks like the differentiator between the name of the old AL lens and this new AL lens is the term "Weather Resistant" in the name. On Pentax Forums (http://www.pentaxforums.com/lensreviews/SMC-Pentax-DA-18-55mm-F3.5-5.6-WR-Weather-Resistant-Version-Zoom-Lens.html), they've labeled the lens "AL WR".
