I call BS. First off, the cited email is from Digicircuits, which appears to just be some third party retailer, and all their orders - like many other third party retailers - are likely being cancelled due to massive amounts of orders received and limited stock (I've have 3 cancelled orders from 3 different places). Second, I have an HP order from last weekend that was finally processed last week Thursday and will be shipping out tomorrow.
I realize this is marked as a rumor, but I hardly find a forum post and facebook comment credible enough to make this front page news forum worthy.
