With Triple H as the special guest referee and Bryan sort of being caught in the midst of this power struggle between himself & Vince, all signs point to this match being where that particular angle kicks into another gear. Otherwise, I'd see no reason for Triple H to be involved.
There's been talk of possibly turning Triple H heel this week and I've also read reports in which the idea of turning him & Steph heel was scrapped weeks ago. If the idea is for Triple H to feud with Vince over control of the company, then I simply don't see it working if Trips turns heel & Vince turns face. Both can't play heels, not in this sort of storyline. If Daniel Bryan is going to play a role in this angle, especially in its initial phases after it's kicked into another gear, then I don't think it'd make sense for Vince to suddenly "come around" to changing his opinion on Bryan and for Triple H to step into Vince's role after Triple H does something to screw over Bryan.
As far as Randy Orton goes, I don't see Orton successfully cashing in tonight if Daniel Bryan wins. I can see Orton trying to cash in but I honestly think that Triple H will somehow screw him before he's able to cash in or screwing him after he cashes in, allowing Bryan to retain. This could be a reason for Orton to turn heel, feeling that Triple H screwed him over, thereby aligning himself with Vince as the sort of champion that Vince feels is right for the company. Since there's talk of some type of match at WM XXX to determine who gets control, I don't know if Triple H will wrestle or if he'll have someone to represent him like Vince would. Orton & Triple H do have a long history but, personally, I'd rather see someone fight for Trips rather than Trips doing it himself with some one representing the "new guard" of Triple H's banner while Orton represents the "old guard" of Vince's banner.
When it's all said and done, however, I think the only way that a lot of people will be disappointed is if John Cena cleanly defeats Daniel Bryan. Even if Orton successfully cashes in MITB 30 seconds later, the wind will be let out of a lot of people's sails. Rumor has it that Cena is taking time off after SummerSlam in order to have surgery on his elbow, so the odds of him walking away as WWE Champion tonight are extremely slim. However, I don't see Cena going over Bryan, certainly not with a clean win. With Cena taking time off, this would be a perfect opportunity to give Bryan a major rub and to ultimately begin a fresh WWE Championship program with Randy Orton. Based on a story I read earlier this week, the rumored main event for Night of Champions is Bryan vs. Orton, though the article made no mention of which one of them would be carrying the title.
If WWE wants to really generate a ton of interest for the final segments of tomorrow's Raw, perhaps tomorrow night would be a better time to wait for Orton to attempt to cash in his MITB contract. If Cena loses, he has an automatic rematch so I could see them setting the return match up for Raw tomorrow night. Orton could interfere in the match, possibly doing further damage to Cena's arm as a means of writing him off television, and attempt to cash in there as Triple H won't be out there as the special ref.
There's several interesting ways of ending this match tonight. As long as Cena doesn't go over cleanly over Bryan, I think most everyone will be excited about the outcome. Otherwise, even if Bryan is still in the picture after having lost to Cena, I don't think the excitement to see what happens next will be nearly as high.
