WWE’s creative team and Vince McMahon are said to be big on Triple H vs. Batista. They feel that while it’s conservative, it’s a proven commodity and would probably be the biggest drawing match they could have. The USA Network, which screens and has a heavy influence on WWE storylines, is pushing for a Randy Orton vs. Batista main event. This of course, was the running plan for WrestleMania 22 until Batista’s injury derailed all plans.
Their belief is that the match up is more fresh. Either way, both sides seem to feel that Batista should be back on the Raw brand and will likely be the man walking out of the big show with the WWE Championship. Early talks involved doing a four way between all four former members of Evolution, however those plans were scrapped. Sentiment within the WWE was that Flair’s final match should be a one-on-one affair.
The Undertaker vs. Edge appears to likely be the “other” big main event for the show, with the company using the undefeated streak of both at WrestleMania as part of the build. It would seem the first seed was planted at Survivor Series during Edge’s return to the company when he attacked Undertaker.
Of course, these plans are almost always subject to change, but for now, this is where the company is at.
