Sony’s latest spearhead, the Xperia Z, hasn’t even enjoyed a proper global release yet, but there might already be a new high-ender on the horizon to join the Xperia family. A mysterious “unrecognized device” with the C6802 model number has been spotted performing an HTML5 test and is most likely going to land in the second half of this year.

Judging by the model number, the upcoming phone should find a cozy higher place on the Android food chain than the Xperia Z (aka C660X). The only specs revealed by today’s leak – a 1,920 x 1,080 pixels resolution panel and Android 4.2 Jelly Bean – are not very different than what the Z packs, but we’re guessing any upgrades Sony is working on will likely focus on the processing speed, RAM and/or battery.

The C6802 should be a regional 3G-only version of the upcoming flagship, while other model numbers, like C6803, C6804 or C6805, should probably pop up soon. Now, before getting too ahead of ourselves, we have to say we’re not entirely convinced the C680X exists.

After all, we only have one screenshot leaked by an anonymous source to the guys at Xperia Blog. The pic could have easily been Photoshopped, either entirely or when it came to the ID and/or user agent.

But why be so suspicious? It’s not like it’s impossible for Sony to be working on the company’s next flagship. In fact, we would be really shocked if the Xperia Z would remain the only big gun throughout 2013. Especially with the Tegra 4, Exynos Octa and Snapdragon 600 and 800 chips so close to their commercial releases.

In any case, only time will tell if Sony’s C680X is real. And what kind of specs it will pack. A Snapdragon 600 or an 800. And whether or not it’ll be waterproof. If it’ll blend. If the alphabet will need to be reinvented in order to make the new guy look better than the Z. So many questions…
