This game, much to the irk of the PC community actually (as this is one of their main complaints), is before all a console game. Out of the 5 million buyers, last I looked, 4 millions played on either Xbox 360 or PS3.
No. Mods will not fix anything. Mods are there to add, not to repair or balance. Most Skyrim players cannot afford to rely on them, because we do not have access to them!
Just my 2 cents, was going nuts

EDIT: Please dont let this turn into a platform war. All 3 platforms are plenty viable, and no one is smarter or dumber for playing on one over the others. We all chose according to our means/preference and thats that.
The bottom line is that this game was sold on 3 platforms, and therefore should work on all 3 just as well. Proposing mods as a solution to balance issues, or bugs/broken quests is problematic, because it is something that fixes the problem for only 1 of those 3 platforms.
Mods will fix alot, just check the other Bethesda games out (that are bugged to hell but fixed with mods).
Sure mods are there to add the "extra" things the players wants. But there are also mods that fixes bugs and whatnot. So saying that MODS are the to add, not to repair or balance is false.
Blame Bethesda for not fixing their games, it's known by alot of people that some bugs won't ever be fixed by Bethesda, small or huge. But it will most >likely< be fixed by the modding community.
It's a shame that console players can't use mods, it really is.
And you're right about all the consoles and PC = viable.
But here's what i do (this is just me and what i prefer).
PS3 = Only exclusive games or games that are NOT ported to the PS3.
Xbox 360 = Multi-platform games, since most games are made for the 360 and later on ported.
Wii = Same as PS3 i guess.
PC = Games that can and will be heavily modded, or some shooters (not all of them). And console [censored] going "i rather sit on my couch than on the chair" that's just *facepalm* Just plug your PC to the flatscreen, plug in a controller (360 or whatever you prefer) and play the game from the couch.
Just my 2 cents.
