Adding yet another phone-tablet hybrid to the pile, Sony has announced the dustproof and waterproof successor to its Xperia Z series. The Xperia Z Ultra is bigger and comes with one of Qualcomm's latest processors, though we're not sure when we'll see it in the US.

The Xperia Z Ultra is bigger than its 5-inch sibling, with a 6.4-inch display and 1080p resolution. Sony says the phone-tablet hybrid weighs about 212 grams, though it manages to maintain a svelte chassis at only 6.5 mm thickness. It also features a 3000 mAh battery pack to power that large display, in addition to a 2.2GHz Qualcomm Snapdragon 800 processor, 2GB of RAM, and 4G LTE connectivity, though no specific band has been mentioned. Additionally, there is 16GB of onboard storage available and a microSD slot for an additional storage of up to 64GB.

Those interested in taking the "phablet" underwater will also be pleased to know that the Xperia Z Ultra features IP55 and IP58 waterproofing, which makes it just a little more resilient than its predecessors. It will also feature Android 4.2 Jelly Bean right out of box, in addition to a slew of other software features like Sony's movie, music, and PlayStation apps. You can also use it to snap photos with its 8-megapixel rear-facing camera and 2-megapixel front-facing camera.

No US date has been set for the Xperia Z Ultra, though the tablet should launch in July in parts of Asia, followed by a European launch sometime in September.
