I didn't really like their last match together, and i have my doubts that they'll be able to carry this thing for an hour.
I expect about 30 minutes of rest holds disguised as mat wrestling, followed by 20 minutes of big moves and little long-term selling with one or two falls, followed by 10 minutes of clusterfuck action, with run-ins and ref bumps galore. I also predict either Vince McMahon or the Undertaker is directly involved in the finish.
