I don't see the point personally, I thought the death in AoU was pointless and made me glad it was Joss Whedon's last job with them. They really only use death in comics for publicity and if it's a long term character that might have gone a bit stale.Personally, I don't think they'll kill him off. I don't think the general public has the tolerance to see these characters get killed off and then resurrected every year. If they kill anyone off, my money is on Robert Downey's character.
They never stay dead long anyway.
