I doubt it. For some reason Tmo USA is slacking in getting a "super" phone to compete with other carriers such as Sprint (w/ the EVO 4G), Verizon (w/ the HTC Incredible), and even AT&T (w/ the Samsung Galaxy S).
There have been whispers of a Samsung Galaxy S Pro (which supposedly has a physical keyboard) to show up in Tmo's inventory, but I'm not getting my hopes up.
If Tmo doesn't get a "super" phone soon, then I'm probably going to end up jumping ship, and get the EVO.
