I'm gonna give Brock/HHH a re-watch right around the corner from Mania and see if I can complete it. I don't know, maybe by some chance the feud to Mania will actually be great and it'll give me more motivation to sit through the whole Summerslam match in anticipation for their Wrestlemania match.
I'll probably do the same with Rock/Cena, though I do think that'll be a lot easier as that match was comfortably better than Brock/HHH to me.
Cody/Goldust never really interested me as much as it should've. I suppose it'd be a fine under-card match to give Cody something to do. May as well give some WM predictions, even some match order and times of matches. We'll have Rock/Cena as the main event, Lesnar/HHH as the sub-main event, Taker/Punk as the big streak match, The Shield against Orton, Sheamus, and Ryback (I'm having my doubts about Orton/Sheamus for Mania now with their being no EC match for The Shield apparently, though I have heard the rumors of Ryback/Jericho), Maybe a World Title triple threat or fatal four way, AJ/Kaitlyn for the Divas Title, Barrett/Jericho for the IC Title, Cesaro/Swagger for the US Title (I still think there may be a Swagger face turn at some point in the next 4-5 weeks), Kane/Bryan, Mysterio/Cara, and Cody/Goldust.
11 matches. That's about right, right? As for order and times each match are given (including any video package, entrances, and after-match celebrations), I'd see it being:
WHC Fatal Four Way (23 minutes)
Swagger/Cesaro (11 minutes)
Cody/Goldust (7 minutes)
Lesnar/HHH (mainly this early for the same reason as Taker/HHH last year, to give a lot of room between it and Rock/Cena) (31 minutes)
Kane/Bryan (13 minutes)
The Shield/Ryback-Orton-Sheamus (26 minutes)
Barrett/Jericho (14 minutes)
Mysterio/Cara (20 minutes)
AJ Lee/Kaitlyn (8 minutes)
Taker/Punk (26 minutes)
Rock/Cena (33 minutes)
That totals 212 minutes, leaving 28 minutes for promos, performances, and whatever, though usually WWE leave 10-15 minutes open at the end, so it really leaves 13-18 minutes, which depending on the amount of performances (if they have any), may not be enough.
