Dont keep your hopes up. I saw the new S5 touchwiz at best buy, I must say it is night and day better than the current touchwiz. If we go by past samsung history I highly doubt we get it. Samsung might update us to latest OS, but their corporate greed gets the best of them when it comes to updating their user interface. I bet they keep it exclusive to S5 and upcoming note 4. Even HTC is promising to update the old M7 to sense 6, even though they never did it before but samsung simply doesn't need to unless they were hurting like HTC. If I had to bet my 2 cents I would say no, we the note 3 owners won't see the new Ui. However I do hope we do.
