ROFL, oh god here we go again with Nash and Newsradio...
Verizon could launch them both in the same time period because they have absolutely no stock in the N1. Who cares if they offer a similar phone and people buy it over the N1. They are still going to buy it and still going to use THEIR service. It would make much less sense for them to offer a phone through a 3rd party (google) and then 3 months later offer their own version of a very similar phone.
I agree with this as well, seems like a logical idea that I didn't think about. That is if Google doesn't agree to let Verizon do in store support, which it doesn't sound like they intend to with anyone.
Edit - What I find funny is that Google is actually being so stubborn about this being their own phone that only they can sell that they are letting it hurt them significantly. Sales are low, people are totally pissed about the lack of support, and other competition is rapidly approaching. These guys need to let it go and give it to the stores.
