I personally hope it has more RAM (like 2GB) so Safari Tabs won't reload so often. I'd love to see more battery juice (like 2000 mAh) unlike 1560 mAh as rumoured. Hello, S4 lasts for a day and a half now. And if the camera is not improved (to 13 MP maybe) and there's no dual flash, I might skip 5S (yes, I'm looking at Nokia 1020 and Sony Honami with 41MP & 20MP cameras). Also, the build quality must be improved, I have a white and black 5 and both have visible scratches and dents though I haven't dropped them and I'm relatively careful with my devices. All other improvements are welcomed, but don't matter to me much. I honestly don't care if it has LTE-a, or wifi-ac, nfc or fingerprint scanner.
