Apparently from what I can find "the casks going into it range from 13 to 30 years old" and "It is a limited edition malt (albeit in an edition of 60,000 bottles), and cannot be repeated".

Hope that helps out a bit. Sounds interesting, seeing as how it is limited I'm sure you it wouldn't hurt to pick up a 3 pack. If I had the cash I would.
