With the "recession" over, I think most reputable labels have moved a great deal of inventory. They're possibly adjusting their production or wary of how much capacity they can reliably store. Less of a need to discount presently.
Also, consider a winery's inventory like a mortgage portfolio, in 2005 they were probably saying, "the more we keep in our library, the more we'll be able to charge down the line [ie, beat costs of storage/inflation/interest]." My guess is that the hit they took will encourage many to hold their juice for even shorter periods of time. YMMV, Just mho.
