One thing to remember, if this turns out to be a nexus device, there will be no ugly Verizon logo on the front, since Google hasn't allowed carrier branding on the front of their devices since they prefer a more streamlined design. Unfortunately, if this turns out to be a Droid device, all bets are off, sadly.
Edit: After a bit of research, Google hasn't allowed carrier branding period, on any of their nexus devices. How sweet would that be to have an un-uglified nexus device on Verizon. Fingers crossed...
The whole "Passing on the GSII for exclusive "Nexus/Prime" device really has me worried though. We heard that the Prime will be on all carrier, right? Which would mean the only way to make an exclusive device would be to add more crap to it. How crappy would it be if they made this whole big deal that VZW was getting an "exclusive beefed up" version of the phone and the general public eats it up and the only real modification is branding on the phone, added bloat, and a locked boot. I get angry just thinking about it. All that plus all the GSII commercials I saw on TV this weekend while watching College Football and the Emmy's made me really sad.
