you see this all the time, verizon will get a euro phone and tweak it a bit. I look for the incredible situation to be just like the hero situation last year. The HTC incredible will be very, very similar to the desire. Just like the eris is very similar to the hero. Sadly, we all know what happens when a euro phone comes out, we usually have to wait a few months. I just hope they start rolling out the 2.1 update before that so we cam get a little taste of the new sense experience. Not to mention I would love to have navigation.
I think the Incredible will make me hold off on getting a nexus. I have to admit, given the option, I would choose sense ui over stock android.
