(Note: I've read the full article - I'm not coming from a place of third-party information. I can provide quotes if necessary.)
At no point in the article did it say that content was race/class/background specific. The most detail they provided in this realm is regarding how the world adapts so you don't inadvertently cut yourself off from a quest. Regardless, I think I trust the developers to balance content in such a way that you don't lose out on too much content by making decisions while still providing that sense of consequence. A world in which you can experience everything is a world in which your decisions mean nothing. I'd rather make choices that have weight. Plus, it'd provide me with just another reason to play the game through again.
Regardless of the fact that the article did not confirm level-scaling (all it confirmed was quest-scaling for auto-generated quests - VERY different concept), I think you need to review history. Every TES game had level scaling of some sort. Morrowind included. Oblivion's level scaling was more drastic than Morrowind's, so the entire Morrowind fanbase got the weird idea that no level scaling existed in Morrowind. It did. Just toned-down in comparison to Oblivion. I would be willing to bet money you've never played an RPG lacking level-scaling of some sort, simply due to the fact that most modern RPGs (modern meaning post-2000) use said systems in some fashion - even if it's subtle.
There are a vast number of ways to implement level-scaling systems, from systems that effect blanket changes to systems that change certain parts of the game but not others, to tweak the difficulty in certain ways or even in certain places. You're jumping to a strange conclusion by assuming that Skyrim has the blanket level-scaling that Oblivion had (which it doesn't - thanks for confirming that GStaff!).
Not even sure what to say here. If you don't like realistic combat, you're in kind of a weird place - historically, every element of TES gameplay has been implemented as realistically as possible. If Skyrim delivered combat similar to Legend of Zelda, I'd be seriously worried about the mental health of the developers.
On dual wielding - you haven't seen it. Did anyone ever tell you it's OK to not form an opinion until there's enough evidence in place to justify doing so? This is one of those times. Until we see it in action, there's no way to know how well it'll work - though, based on how far into development they are, I'm guessing the answer is "very well." If it didn't, they probably would have cut it by now.
"Did anyone ever tell you it's OK to not form an opinion until there's enough evidence in place to justify doing so?"
"Most likely it means these aspects went neglected"? Once again, you're jumping to conclusions. There's plenty they haven't revealed - we've got a ton of general information, but very few specific details on systems and the like. So, until those things come along, don't assume they don't exist. That's kind of ridiculous.
