I read the news article about the Director's Cut of The Abbey, and this line has caught my attention:

The trend towards updated Director's Cuts of older adventure games continues

Is there a list somewhere of these enhanced versions and the changes they introduce?
If not, perhaps we can start one here

Broken Sword: shadow of the templars (Director's cut for the Wii)

[Origami]

Errmm...not really adventure, but Silent Hill 2 had a clear Director's Cut

[Origami]

Owh wait....there is a re-release of Shadow of Memories for the PSP that has some revised art and a small portion of added content.

Scratches and the first two Dark Falls also spring to mind.

I was lumping the Sherlock Holmes "remastered" versions in this category, too, though they aren't technically Director's Cuts with new scenes added. Monkey Island SE as well.

Not really new but: "Jack Orlando Director's Cut"

Telltale Games also did a DC edition of the Bone games. At least the first has a proper director's cut, I don't know what they added to the second game though.
