I don't know about this.
The 9th was a pretty set in stone date until issues cropped up at the last minute. There were emails leaked, stock in stores. Frankly, I think Verizon is planning on releasing it with little fanfare.
I know there's a TON of excitement here on this board, and I'll be at my store at 9 AM Thursday (unless we hear something different), but the Nexus is a phone that is intended for developers. The Nexus S didn't have a huge release and I don't expect this one to either. It seems like a huge release because we're an insulated group of extremely excited tech geeks/nerds but outside of us, there isn't a ton of buzz.
Ask 100 people on the street about the phone and 95 of them will probably have never heard of it, or if they have, don't see why it's any different from a Razr, Rezound, Bionic, or iPhone.
I'm excited, but I think we believe this phone SHOULD be promoted. But to the layman, it's just another phone.
