there will be maybe a third season of dark Angel ??

I don't think so!!! but I'm hopeful...as we all are!!! :) DA is still alive

no, sorry. the end of 2 season depressed me, i couldn't believe they already gave up, but there will be no following. though there's a film for dark angel, and a book that tells us the end of the story.

I doubt it. I think James Cameron produced it and had a hand in directing the first season and he has long since moved on.
