Saw the same thing, it won't even let me log back in. I guess I'm out. Matter of fact, that is the only device that doesn't have an "add to cart" button.
Ive been in since 11:50 and I think the add to cart button still didn't exist. The 64gb tab has an add to cart button. All I know is that when I refreshed at midnight EST on the link for the 32gb dv8p. It stated that because of high site traffic there was a delay.
