Will we ever see group content that isn't a dungeon on rails?

Directionally challenged players had a very "fun" time finding their way to where they needed to be and I know one elderly Guild Leader I had could never find his way around.

This reminds me of the developer commentary for Half Life 2: Episode 2 where they told the story of a play tester literally going in circles for 30 minutes inside a cave. Valve decided to make areas more linear because of it and both Left 4 Dead games are all about running down a linear path every time.
