Expected date of release of 4.3 android version sony experia m (C1905)

HI, I want to know the date of release of 4.3 android version for my Sony Experia M. I am using this handset from some months and didn't find any kind of update in my phone's update center. I also want to know that how can i update my android version when it finally release ?

I don't think you will ever receive update for Android 4.3 in Xperia M as there is no news and company only works for latest updates on higher end phones.

Infact you should look fro 4.4 Kitkat update, it will make your phone faster.
