I was about to agree, but then I looked at what the Nexus releases have been like so far:
- T-Mobile was the first one to carry the three Nexus phones: HTC G1, HTC Nexus One, and Samsung Nexus S (I count the G1 because it was a phone that was developed with Google's help).
- AT&T carried the Nexus One and Nexus S after T-Mobile had received them (only a few months in between releases)
- Sprint only has the Nexus S 4G, but did receive it before AT&T (May 8th for Sprint, July 24th for AT&T)
Its possible that Verizon could be the one to get it first in the USA then it subsequently roll down the hill to the other three major carriers. Big Red skipped over the Galaxy S II phones specifically for this one, so there had to be something going on prior to the Galaxy Nexus announcement. I won't say lottery though, I'll just say some kind of selection process.
Hope this helps!
