The fact that Samsung just made LTE 800Mhz phone using pretty much the same baseband silicon that was designed two years ago, and still managed to make a sleek design, I don't see why wouldn't the same exact LTE phone come out in the U.S. on the 700Mhz band 13... I was actually hoping that the new 28nm Qualcomm chipsets would come out earlier, so that power consumption is lower, and battery life longer, but it looks like Samsung managed to make a beautiful thin LTE phone.
Now I'm convinced we will be getting 700Mhz GS2 in a month!!! wow!
