Myself and a friend were by a local Best Buy Apple store today and he was thinking about picking up an apple cinema display to compliment his mac. They were out of the 20 incher he wanted so they offered to customer fulfill one for him and have it delivered to his house. He said sure, he'd appreciate it. Only, when they looked it up in the system they noticed that not only did they not have any currently in stock, but that Best Buy wasn't expecting to get any more of the cinema displays in anytime soon. The last time this happened was right before the iMac refresh, otherwise they can always order new displays/macs, etc, it just may take awhile to fulfill it. The general impression everyone got was that a very likely reason they would be out of stock would be because a refresh was coming soon, likely with the launch of leopard. It's worth noting the same situation exists right now with Best Buy regular Macbook laptops, and a minor refresh to the Macbook is also generally expected with the Leopard Launch. Anyway, take this with a grain of salt, but it is a possible indicator.
