- It'll look pretty much identical as has been the case with all the *S models.
- Camera may get a slight increase in MP, but really it's getting high enough, better sensors as usual though.
- Faster as always.
- Still no NFC. (Because I've never seen anywhere I could use NFC to buy things or do anything. Apple doesn't do "checklist" items just to do them, they wait to do them right.)
None of those are that huge, I'd guess the bigger thing will be increase in the capacity. 32/64/128GB sizes.
It'll be interesting to see when the speed/battery trade off starts to switch the other way. This year they went for doubling the speed while keeping the battery life the same. What if next year it is a minor speed increase, but doubles the battery life?
