Weren't you aware of the impending release when you ordered it? 😕 If you spend much time around here, it shouldn't be a surprise that a new model will be out later this spring or during the summer. In terms of this article, wasn't it digi-times that said last week that most fo the ivy-bridge processors wouldn't be released until July, only to be debunked? I'd take it with a grain of salt.
No one knows when the new airs will come out. Best case scenario is still 2-3 months away. If you want to wait, just send it back. But it shouldn't be a surprise that new ones will be coming out in X amount of months.
