I'd like to see Henry as champion but not under these terms. If Batista regains the title then Henry should win it off of him. Kennedy will get his chance but right now it's too early, by SummerSlam time yes.
Henry will obviously return and challenge Batista. If not, Finlay will probably be a condender for the next month, jus until WWE figures out what they are doing.
Batista is out of the title hunt. Flat out, just like Edge Orton HBK are out from Khali, Batista will be out of Judgement Day, I place my bet on Mark Henry, renewing that rivalry might be a good thing.
Batista/Henry should not be for the WHC title though, Henry should come out and cost Batista his cage match next week, destroying him just like he did way back in his debut during the Batista/Mysterio vs MnM cage match. The following week it should be a triple threat WHC title match in which Taker retains. And then the following week after that Taker should be backstage doing his shadow boxing when Mark Henry (could've had the mystery effect but they ruined it by using it for Kahli) attacks Taker brutally. An update later in the night says Taker is severely injured (and say w/e the injury is), and that he will need to drop the belt. They then have a small tournament leading up to Judgement Day where it ends up being Mark Henry vs Batista (no holds barred), Mark Henry winning. I have some ideas on Kennedy being involved with Judgement day or shortly after but not a clear one yet.
