I think their best way to go with Bound For Glory would be Aries vs fresh opponent (AJ or Angle likely) + Roode vs Storm in a grudge match.
I think AJ would be great in the long run some way somehow but he's still mixed into the Claire story and that won't work well in the championship scene and something I can't imagine current TNA doing.
Aries vs. Angle has the making of a great feud and match that would be great as a victory over Angle would strengthen Aries' reign and legitimacy. Also, Angle's career is going to wrap up soon and I'm sure he's looking to put the new faces of the company over as he always has.
With that said, I'm hoping Storm is behind Aces and 8s. I don't find Storm that interesting but I can see a heel turn churn out some good stuff with a stable in the picture as well. Storm will be worked into the world title picture but they aren't going to kill Aries' run. This win tonight kinda proved that for me.
What happens to Roode though? Other than possibly retiring Sting, Roode should stay constant in the main event picture. I mean c'mon... that boss theme.
