Anyone waiting for the enhanced smart covers with the back protection? The Apple site still only offers the ipad 2 cover (front only). The apple store says the ipad 2 cover will fit and I can return once the enhanced cover is released. Does Apple typically release the covers the same time as the product? It doesn't make sense they recommend the ipad 2 cover during the preorder without the option of also preordering the enhanced smart cover. For people that bought the ipad 2 on launch, was the smart cover announced at the same time?
