We didn’t see a new phone from Sony at MWC this year, though it did take the opportunity to show off the Xperia Z it demoed early this year at CES, but a new rumor suggests we’ll see a mid-year upgrade in a few months time that packs Android 4.2, a Qualcomm Snapdragon 600 chipset with 1.8GHz processor, 2GB of RAM and 32GB of onboard storage.
