Well, there's a reason why the Rezound was deemed as the Thunderbolt 2 originally and also good reason why it was renamed as well.
1.) They knew the Thunderbolt was a little behind the times by the time they got it out the door, which they continue trying to fix some small wrinkles to this day.
(fine, devs have made most issues go away)
2.) Easier then making that device function as they intended, they released a new revision of it: The HTC Rezound(Tbolt 2)
3.) They knew with the shortcomings and delay of the Thunderbolt, it would have likely been a huge ordeal if the Thunderbolt 2(Thunderbolt HD) came out that shortly after the Thunderbolt original. Not to mention the name may have turned away anyone that had bad feelings about the Thunderbolt launch.
Anyway, I guess my point is that the Rezound was originally intended as a replacement for the Thunderbolt, so that they could phase it out that much faster, having a similar device to fill the void.
But all of this is based on my readings and opinions and am just sharing my point of view on it.
I wouldn't sacrifice my Bolt for a Rezound, much the same as I won't pay full retail for the Inc 4G LTE(VZW gimped HTC One wanna-be)
or lose my Unlimited over it at a discount.
They(VZW) keep shooting HTC in the foot....way to go Big Red.
I sure hope the One XXL does come to Verizon(as rumored), as that's the only device I have heard any word about, that sounds worthy of my money for full retail price in the near future.
