+1, I think Ill have my EVO for a while. I dont see any point in upgrading until I see higher res screen, dual core cpu and better gpu. I would prefer it came in the same exact shell as my current EVO as well!
On the other hand, I am trying to get my friend into an Android set and he is on Verizon, so this "Thunderbolt" looks very promising. I have played with a Droid X as well as the Galaxy phones, HTC definitely has the best UI out of the 3 and seems to be way easier to root and toy around with. I cant wait to see what HTC is doing for Sprint in Q2-3!
