4.3 does I have a note 3 with 4.3 and it let's me put apps to my SD card. Now I don't know if that's all 4.3 doing or if it's the combo of the note 3 and 4.3.
4.3 does come with the ability to move apps to SD card. I don't have the link but Samsung posted the official 4.3 update loge for the note 2 and that was the only thing that made me really care about the 4.3 update
