A marginal firmware update for the Xperia L (C2104, C2105) has been certified by the PTCRB. Firmware build 15.3.A.0.27 is a minor bug-fixing update over the current Android 4.2.2 build (15.3.A.0.26). If this does see the light of the day, expect it to hit handsets within the next few week.
Thanks Ben!
