I noticed that today as well. I'm calling around, asking Staples and Best Buy if anyone's got one in (on a blind hope).
But maybe I'll just wait for the mythic MeMo Pad 7 HD. It's a lot cheaper. Plus SD port, mothafuckas.
I work at Staples(in NYC) and Google just gave us the green light to start selling the Nexus now. They wanted us too wait till August before putting it on shelves in the store.
It will be available probably by Monday in stores and I'm pretty sure that's going to be nationwide.
