I certainly hope this isn't the case but: I was just perusing Google looking for MC743ZM/A, the model number for the 5870 upgrade card. I noticed the following: 1) CDW says "product discontinued as of Sept 23, 2010" http://www.cdw.com/shop/products/default.aspx?EDC=2192747 2) Amazon says "We don't know when or if this item will be back in stock." http://www.amazon.com/Apple-ATI-5870-Standalone-MC743ZM/dp/B003Z6QH6W/ 3) Tekserve.com used to list the item, now it disappeared. Yes, I am aware that Apple's online store still lists the item, though it's still "unavailable". But I just found it odd that the 3rd party merchants I mentioned above seem to indicate it's been discontinued even before it was released.
