I'd say the part I'm most curious about is if Light (or his equivalent) will be portrayed as a tragic hero or a villain. I felt that the original anime somewhat dropped the ball there, as the manga made it pretty blatant that he was a villain, while the anime gave him a much more "noble" ending (I recall reading that even the author of the manga was a bit annoyed with the change). I guess I can understand why that would be changed, since it makes the character more sympathetic, but I generally prefer see adaptations at least be consistent thematically.
I suppose I'll wait and see about this one...but I'm not very optimistic right now. At least it's not Dragonball: Evolution.
