First, I'm curious if this is official. I mean, originally it was: Batista v. Great Khali v. Mark Henry v. Undertaker. Then it was Batista v. Rey Mysterio v. Finlay v. Undertaker. Now they've cut out the two inter-changables & went with a single's match. So here's my take on this match-up.
World Heavyweight Champion: Batista v. Undertaker:
Fan's Choice: Special Ref. A.) Steve Austin B.) Mick Foley C.) J.B.L.
My Opinion: Ultimately, I don't think it matters who's involved in the actual match. Batista, in my mind, will retain the Championship because Edge will make his (surprise) return at the end, & cost Undertaker the match - setting up Edge v. Batista at Survivor Series. I could be wrong, but more or less, Edge returning & spearing the "Champion" (whomever it'll be) will likely be the ending.
As for the Special Ref. - Why would J.B.L. even still be considered for this match? Rey isn't in it. Apparently the J.B.L./Mysterio angle has been dropped, or lost in a shuffle.. as Finlay is now Rey's #1. enemy & J.B.L. is being dealt off the deck in a voting poll he couldn't possibly win.
Mick Foley hasn't even remotely been around lately, & when he has been, what connection does he possibly have to this match? J.B.L. MAY get more votes than Foley, simply because "smart" fans wouldn't know why Foley'd even be involved.
Finally, smart fans, mark fans, dumb fans, it won't matter. Landslide - Steve Austin. You can slap his name in a "who do you want in a bra & panties match?" poll, & everyone would still vote Austin, simply because his name draws. People want to see him.. (hopefully never in a B&P match, but still)
Final result: Edge spears the Champion, sets up a title match at the next p.p.v. - Steve Austin stuns Edge, fans cheer, segment over.
