As Sony looks to revitalise its Xperia sub-division this year, rumour has it that it will attempt to do so by releasing the world's first 5G and 4K OLED smartphone. The company's next flagship, supposedly called the Xperia 2, will feature a host of other flagship hardware too.

So Xperia 0 was a far off rumor.
Not unexpected, I must say, as it causes great difficulty in naming its successor.
i hope they fix the heating problem. i had 2 sony smartphone. both have the same issue. it gets easily heated. and once its hot the camera is shutting down.
