I find it a pretty logical line of thought.
I find it hard to believe that Bungie would dedicate anybody to asset creation for D1 while they are sure as fuck crunching on D2 right now.
So whatever the Live team comes up with would have to deal with available content.
Bringing old Raids to current LL would be a huge crowd pleaser, a deserving sendoff and would set a really positive mood while waiting for D2.
MARK MY WORDS!
Gonna have to disagree with that. More old content. Yay!
