All Verizon would do is give you one of their thousands of...how do they say it? The refurbished ones that go through the "1 billion point inspection". That's how I got 4 or 5 devices so far with dead pixels, as a replacement for a device with bad pixels. I sincerely doubt they will ever give you a new Thunderbolt 2 no matter how much you demand it, unless you get some insane off-the-line manager at a store, but if you succeed that would be awesome indeed!
And as for the Bionic and Thunderbolt 2 and all these new phones...I could give a crap less...I had a Droid Charge for 2 weeks before switching to my Thunderbolt...the Charge was so flimsy, and while it had good battery life, I think most of that was just the fact that everything was black with white or brown writing. The Thunderbolt seems like a computer, the Charge was a toy...good for my mom. Not me...and I'm glad I got the Thunderbolt, added on a 3200 maH (?) battery and a Seido case and I'm good to go finally. But I do eventually want to get one with a non-dead pixel but at this point, I really doubt I'll ever get a replacement phone without one. I went through several new ones at the store that all had a dead pixel. But my point was - there's always something "better" coming around the corner hehe....as long as you're happy with your phone then that's all that matters.
As I see it, the phones will be supported 2 years past the date they are given out still - at least in an ideal world - so that Verizon doesn't have to be bothered with claims of "then give me a Thunderbolt 2". Once 2 years go buy, they expect everyone to either deal with an unsupported phone, or upgrade.
