It's "supposed" to be no larger than the Bionic or any of the other "average" sized 4.3 inch phones. The difference will be in the absence of a bezel. Most of the face of this device will be usable screen unlike every other phone out now.
I never said it was going to be larger or smaller compared to any phone. I just said I know people that won't be it because of how large it is. I know people for instance, who won't buy anything over a 4" screen.
