I think it's a good looking phone and would take a good long look at a GPE version, until I saw the dimensions. It's significantly bigger than both the HTC One and Galaxy S4, two devices I place at the limit of my preferred size.
Shame too, because we spend a lot of time outdoors (beach, pool, park) and coupled with the daily Florida afternoon thunderstorms, was excited about the waterproof nature of the device.
The size is a big turn off for me too, especially since the square-design doesn't lend a very ergonomic or comfortable hold. The fact that it's bigger than the current Z is a little frustrating too.
Is there any reason why it's bigger? I suspect the 20.7 MP camera might having something to do with it?
Despite that, I'm interested in a GPE of the Xperia. I'll determine whether the size bothers me or not when I actually handle one in person.
I've always wanted a better camera and home-screen buttons (and a side power button). Along with stock Android and timely updates from Google, the GPE Xperia could be a winner. It's probably one of my favorite designs too. Everything about it screams upscale, powerful, classy -- especially the white one. If there is no GPE, though, I likely won't bother.
I can't wait for reviews.

Serious question, where is the USB port?
