I'm assuming this is also the one that will allow you to request a box code on regular orders (if you can get your hands on a current inventory list). It's only fairly recently that they started pushing three year-old boxes into the "vintage" section. But at the same time their pricing on open-stock has become more competitive, pretty much across the board. And the "vintage" pricing does vary with age, going higher on older items.
They've had a vintage section all along, but it used to be populated with, say, five or six year boxes and older. There's little doubt in my mind that this is all related... improve general pricing, but get a little extra out of anything older than about two years on 'em (or in some cases a lot).
All in all, I don't think it's meant to be a statement on aging limits. While the newer Cuban tobacco hybrids may not be as distinctive or require as much aging as it once did, for the most part it still does benefit from long-term aging, or at the very least hold up to it better than most NC's.
