Sony CEO Kaz Hirai had some good news to deliver on stage at D11 -- for US fans, at least. According to him, the Xperia Z, which currently serves as the company's flagship smartphone, is expected to arrive on a US carrier shortly. Unfortunately that's the extent of the details Kaz was willing to offer up, as we expect he wants to give the unnamed operator the opportunity to make the announcement itself. With that said, we have our suspicions that T-Mobile may be involved, thanks to its recent appearance in the FCC with T-Mobile radios. He did, however, mention that this success story is in part thanks to the company's increased marketing efforts in this part of the globe. We'll keep you updated with the news as it trickles out.

Update: David Beren from TmoNews grabbed a few shots of the Xperia Z with T-Mo branding, which certainly adds credence to our suspicions that the Z will wind up with the UnCarrier.
