Sony road map includes Sony Xperia A, Sony Xperia UL and "Togari"
Also on the road map is the Sony Xperia UL (which is codenamed "Gaga"), a phone that is similar to the Sony Xperia ZL but with the Qualcomm Snapdragon 600 powering the device rather than the Qualcomm Snapdragon S4 Pro. 32GB of native storage, 2GB of RAM, and a 2300mAh battery are included along with 1Seg Japanese TV and NFC support.
The rumored phablet is codenamed the Togari and is supposedly scheduled to launch later this year on Docomo. The device is rumored to have a 6.4 inch screen with 1080p resolution and is expected to go up against the Samsung GALAXY Note III when that device is eventually introduced and launched. Of the three models, this is the one that has actually been seen in public; an earlier rumor that we passed along showed that the Togari is expected to be powered by a Qualcomm Snapdragon 800 processor with a 3500mAh battery keeping the lights on.
