Yes, it did. But from one point of view, just like the changes made to Smithing (to bring it into line with how the other crafting profs leveled), the "addition" of kill-cams for magic and archery was more of a "finally finishing something they started", rather than work on a "new thing". (Think about it - there were kill-cams for melee combat, but not the other two types? That sounds like an unfinished feature.)
edit: also, this is patched in content. They'd never hack together an entirely new combat system (and be honest - making the combat have "realistic" physics and locational damage would be revamping it from the ground up), isn't going to happen in a patch. That's "maybe the next game" type stuff.
And since we're on kill-cams - yeah, that's another 'action game' feature that the "OMG, TES isn't an RPG anymore." crowd was moaning about for months.
I like the part where you forget that they added new kill-cam moves. I hate repeating myself, but anyhow, like I've said before, I don't expect a new from the ground up system. However, them working on kill-cam moves is very telling if you're an observant person. Like I've said before, time spent doing animation work for new kill-cam moves is time better spent doing anything else. Anything. Even taking a doo-doo.
And kill-cams aren't an "action game" feature. It's a Call of Duty feature.
The theory is that, the more you base combat on player skill (rather than character skill), the more "action" and less "RPG" it is. Putting in a locational melee combat system that's all about "whack him in the head! He'll die instantly every time, woohoo!

" is a big shift towards player skill. (Not to say that the TES series hasn't had some level of player skill involved in it's combat. But the balance between the two is what the die-hard RPGer's seem to keep an eye on.)
Die-hard RPGers aren't playing Skyrim. If anything, they're playing Morrowind or Daggerfall. If a TES game at all in any case. I don't much care for these crackpot theories in either case. The Elder Scrolls has always been a first person action RPG. People tend to overlook this because the combat systems tend to svck rather badly when compared to other combat systems that are far better in other games.
Having a better combat system is just logical progression. Whether or not it adds more emphasis on player skill is moot. You can take nearly any combat system that was ever made and tear it apart and make it RPGish. Mount and Blade has proven combat and it also has RPG components. It's all about how creative a developer gets when looking at a solid combat system. Picking and choosing what to ... for lack of a better term, RPG-ify.
Skryim already does this to some extent, but the core combat system is lacking. Things like having to unlock Quick Reflexes or Block Runner. Having perks to make weapon speeds faster or more damaging. Things of that nature.
In any case, I never said I was for melee based locational damage. At least not with Skyrim in it's current state. Like I've said before (And I'm repeating myself because a lot of posters don't like to read the thread they post in), Skyrim's melee combat system doesn't support a precision aiming play-style very well. Locational damage would only be of use to archery, that's it.
uh... welcome to every game ever...
Ignorance at it's finest.
