First off, I want to say that I did do a search but couldn't find what I was looking for, so please forgive me if it's somewhere on the second page.

Obviously there will be conflict between the Empire and Stormcloaks, but will there be conflicts between the professional factions(Companions, College, Thieve's Guild, Dark Brotherhood) that will force us to choose between them?

There will be conflict between Thieves Guild and Dark Brotherhood. You won't be able to finish their quest lines in the same playthrough.

The Companions have a conflict between a faction known as the Silver Hand.

I'm guessing they aren't called that because they love werecreatures. Although I guess they'd still want to hug them.

Can I have some confirmation on this? This is kind of a big deal! I'm not sure I like having to split my rogue character in two.
