There have been multiple rumors that the Sony Xperia Z is coming to US this year, and now we have one more confirmation from some leaked T-mobile support documents that point to the Xperia Z being released soon. Sony's CEO said the phone will be available in US, but he never mentioned a carrier, but now we know that it's going to be T-mobile.
Sony hasn't had a ton of luck with US carriers so far in US, and the fact that they haven't made all that impressive flagships so far probably didn't help. Even the Sony Xperia Z will be arriving much later than it should in US, when people are already considering waiting for next generation devices, like the Motorola X.
Sony is rumored to launch another flagship this fall, probably around the IFA event in September, but who knows if it will be available this year in US. This new flagship, the Sony Honami, is supposed to be the first of a new line-up of smartphones from Sony, made under the "One Sony" division. It should have a new design style, a quantum dots display, and a pixel-binning camera with a huge point-and-shoot 1/1.6" size sensor.
That should make Sony Honami the Android phone with the best camera on the market, by far, especially considering Sony is usually the one selling the sensors to companies like Samsung and Apple, that they use in the Galaxy S4 and iPhone 5. It's just that so far Sony's camera firmware hasn't been the best. But rumors say this time they will also be using algorithms and lenses from their Sony G point and shoots, so we might be very well looking at a phone that will be taking photos that rival current high-end point and shoots.
As I said, it will depend on whether Sony can improve its relationship with US carriers, if they will want to release this phone in US this year. Hopefully, the launching of the Xperia Z in US will show them that Sony's phones can be in-demand, and they will take a closer look at the next one. Otherwise, Sony may just continue selling its flagships unlocked in US.
