does anyone know when is OnePlus 10 pro getting Android 13 or oxygen OS13?

So I was told via chat that it would be out by the end of the month. Here we are and still no update. Believe this is the only version of the 10 pro that has not seen the Android 13 update. Just read that Samsung has released their Android 13 update. So we were right behind Google in releasing 13, but T-Mobile for whatever reason has not released for their carrier version. What's the delay?
