What more would you improve now from the SGS3?

So only a few more months for the SGS4 to be announced and released. The SGS3 is now almost a year old.

I gotta say I'm very happy and satisfied with the phone right now. I like the hardware and the new software features like the multi window, blocking mode, etc. Also the overall speed is better after some adjustments.

So my doubt right now is... are we approaching the SGS3 end cycle? I guess we will receive 4.2 and that would be it.

I personally don't see much reason to upgrade to the SGS4. I don't need a 1080p screen. I don't think I would notice that much difference between that and the SGS3 720p screen. Also I don't think the new CPU or GPU will matter much if games are not optimised. More RAM is not useful unless they get rid of the home refresh either. If probably would still happen with those 2GB RAM...

So what would I improve of the SGS3?

1. I hope we get android 5.0, since 4.2 doesn't bring nothing new to the SGS3 except lockscreen widgets.

2. The new 3000 battery. In waiting to see someone review it. My battery is good, but who wouldn't want even more?

What would you improve right now of the SGS3 after one year with it?
