After taking a week to crunch the numbers, look at the data points and put together some fancy pie charts (we assume), Sony's finally ready to reveal its initial firmware upgrade plans. Five devices in the lineup made the cut to receive Android 4.4 KitKat at a to-be-determined future date, and ten in total are slated to get Android 4.3 Jelly Bean starting next month. Among the devices listed to get KitKat are the Xperia Z, Z1, Z Ultra and Tablet Z, though they'll receive 4.3 first alongside five other smartphones (including a trio of handsets that will jump a version from 4.1 to 4.3). While the rollout is set to begin next month, phones on different carriers or in different parts of the world may not get the upgrade right away. Sony doesn't appear to have closed the door on the remote possibility of other models getting updated, but as usual, we don't have high expectations of that happening. We've included the full list of eligible devices below.
