I'd say this is completely wrong. TES's main focus may not be combat, but if it's not it's very definitely the second-biggest focus. Yes, 'exploration' (AKA 'hiking') is what TES games are truly about, but Combat is the only way to finish almost every single quest in previous TES games. That doesn't appear to have changed in Skyrim.
Since every single part of the game is dedicated to killing enemies and taking their stuff, I'd say TES is very definitely 'about combat'.
TES certainly isn't about the story, interesting characters, or interesting quests - all of those things are extremely sub-standard in past Bethesda titles, compared with other RPGs.
But yes, Skyrim's combat looks like crap. Enemies don't need to stagger in order to show that they've been hit. Further, you shouldn't need to hit them fifty times to kill them; HP soaking enemies are a stupid idea in general. Allow enemies to parry, dodge, or block your blows. Have the stabs and slashes you do to them actually show up on their models. Create animations where they actually react to your blows realistically. It would be different, sure, but it'd also be better - and it's not impossible, either.
Also, the finishing blows look rather bad. The Witcher 2 did them much better, mainly through having vastly better animations.
I'm still going to get Skyrim - I like the TES games for the modding potential and the open-world nature of them, but that doesn't mean Skyrim couldn't be better than it is, just like most games could be better in some ways.
