Yes, I am looking forwarded to it but could easily see being disappointed. I currently use the Note 3. It has been great. Used the Tweaked rom which has a large number of major modifications to greatly improve its functionality. There is very good support with themes and with Xposed modules some additional customizations make it nicer to use. I also can run Fedora and Ubuntu on it. Quite handy at times.

Besides the usual stuff like better performance. The main things I'd like to see are better camera, especillay low light, sound could be improved, a slightly wider screen. Rumoured improvements in screen resolution sound good. All the tech improvements should be good but what should not be overlooked is the ui and how well mail, text, phone, social media and such are integrated. Also look forward to Android L which will not come on it initially. I guess I could go on, but those are some of the biggies.
