All I know is that there was an alleged 15,800 sellout (though Puroresufan.com says it was more like 10,000) at Nippon Budokan, and the match was about 20:09 long. They say it was a pretty slow match, and Hashimoto won it with a brainbuster.
I don't know how to linkify, but check out Puroresufan.com, they have some info on the show.
My unlikely scenario had Lesnar holding the title through WM and Punk winning the Rumble, but Brock is only contracted for 3 matches per April to April, so probably not feasible. Failing that, I guess Orton vs.
