Don't quote me on this because I could be wrong, but I think I saw that ranged units don't have ZOC. (I think Ed Beach was mentioning it or someone in one of the vids).
Also stealth_nsk is right, Swordsmen have no direct counter, and it's logical that like their warrior breathren they get a bonus vs. spearmen units. This is very important, a lot of times most people preferred crossbowmen to macemen in Civ4 even though it was weaker, simply because crossbowmen had no counter whereas macemen did.
Two other things would be:
- Different promotion paths: I think cavalry pomotion lines were more specific, IIRC one was bonus vs. archers, another bonus vs. fortified units. The first line of upgrade on Warriors (and by association Swords) was an all round bonus vs. ranged and melee units on land.
- There were some other things in civ5 that made melee-inf. different than cav: 1) They get defensive bonuses from terrain 2) Cav got penalty attacking cities
