Only 4 devcies are left without android 4.3 update as mentioned by Sony viz. Xperia SP, Xperia T, Xperia TX and Xperia V. A while ago we saw new android 4.3 12.1.A.0.256 firmware Certified for Xperia SP again, previous build certified was 12.1.A.0.253. On 31st December we saw Android 4.3 9.2.A.0.276 firmware getting certified for Xperia T and Xperia V and nothing for Xperia TX yet. But there has been revision to previous certified build for Xperia T and Xperia V.
We just spotted new Android 4.3 9.2.A.0.278 firmware certified for Xperia T and Xperia V and nothing for Xperia TX yet on PTCRB website. It seems this revised build is a bug fixing update of previous build and should come soon anytime now. Have a look at the certification below.

Android 4.3 9.2.A.0.278 firmware certified for both Xperia T variants LT30p and LT30a.
Android 4.3 9.2.A.0.278 firmware certified for Xperia V LT25i
As today only Xperia T, V and SP got revised firmware certification it seems Sony is planning to release all 3 at the same time and we hope we see soon android 4.3 firmware certification for Xperia TX also.
