Support for Sony XPERIA T3 on the end?

So it looks like that XPERIA T3 is totally dead smartphone for Sony Mobile company. Stylish smartphone with was very expensive long time, but support from Sony Mobile is long time on zero. In last weeks there was one new firmware certified - 18.1.A.2.32. Than it was released, but it is only carrier update for Orange Poland with no improvements. So still only Android 4.4.4 KitKat and i am not sure, if this is not stop for XPERIA T3. Really don't understand, why no Android 5.1 Lollipop for it. Sony XPERIA M2 get this update and it cost half of money... But i understand, that XPERIA M2/XPERIA M2 Aqua was much more popular...
