like in the Topic title..
I'm wondering since this is a game coming out on PC,360 and PS3. Will there be Achievements/Trophies within the game, sinse that's not possible on PC?
And how many in that case?

And I also woundering if the game will support 3D witch is the big hype on the market now. Exploring Skyrim on a 3D-tv would be Awesome! or what do you think?

3D isn't exactly a big hype on the market right now.

And yes, there will be achievements, but they won't just be like the basic ones in Oblivion.

Yes and no.

Every full title on the 360 HAS to have achievements. The only question is how many will be story based, and how many will be gameplay based?

Yes, there will be achievements. Pretty much every 360 game these days has achievements.

3D support...

This is a fad that needs to die.

gamesas has other more pressing issues to deal with than to worry about something only 5% of all buyers will even be able to experience (if that).

I can't speak for gaming, but I've read articles that say, in film, it's going to become more common.
