I don't think Bryan walks out as champion. The two options are a draw and Orton winning through interference. If it is a draw then they can decide the champion inside Hell in a Cell which is logical. If Orton wins (with The Shield or Big Show interfering) then they can build to one last match at Hell in a Cell with either Bryan finally winning or him being screwed and setting a feud with HHH.
I personally think Orton wins with The Big Show getting involved.
