That's been announced already.
I think the pieces are lining up for this to be an Evo 3d/Evo2 announcement. Both Sprint and HTC better start showing some cards because at both CES and MWC, neither one of them had anything worth a cent to show. The Thunderbolt on Verizon is just an updated Evo. Here is there chance to do it right. I don't even care if they don't increase the screen resolution to qHD, most people can't even tell the difference and all it does is slow things down 3d graphicswise because the phone has to push more pixels around.
Another nice thing to mention, the new Snapdragons are the only ones that passed Netflix security scrutiny, so that would be the android killer app to show off on the Evo2!
Add in some fancy 3d, and it will be the talk of CTIA and result in me being one happy camper!!
Hopefully they will bake in a nice version of HTC Sense as well!
