It not that long since the release of the Xperia Z2, but Sony here is too excited to release another flagship device.
Sony tweeted on it's Twitter account a little tease of it's upcoming flagship device, and tweet says "Shh… do you want to know a secret? Stay tuned for the next big thing this season". together with a photo of the side of a thin and slim device.
There is no official word on what the device would be or be called. And speculations states that it would be the Xperia Z2 Ultra, though that might be safe to assume due to that the Xperia Z Ultra is also launched around June last year.
