I want a better battery. thats the biggest issue for me and is enough alone to prompt an upgrade, even at full price, if they improve it dramatically like they did with the new computers. I want a bigger screen because it would be easier for me to read, but I doubt thats coming. if it does though, its also something that would prompt me to upgrade without question. increasing the storage is something I very much want but if that's literally all they did, I couldn't justify an upgrade. same for the fingerprints and camera improvements. if they do all three, then its getting very tempting. Then there's other stuff like a faster CPU and such that I don't care about and definitely wouldn't prompt me to upgrade. the phone 5 is already pretty fast, so if thats all they did to the 5S was made it faster I wouldn't bother upgrading. I'm in wait and see mode right now. What will apple bring to the table? I hope they've been on the ball.
