Hmm, seems quite intriguing. On one hand you have Mr. Porter, one of the most plodding, slow paced, boring workers to happen upon the WWE in recent memory. On the other hand you have Mr. Callawy, who seems to disappear for like, a long time, every now and then and when he does wrestle he, well, kind of is pretty boring and sucks, except for when everyone gets all excited at Wrestlemania and whatnot.
So the answer is yes I obviously want to see this, the fight over who is the true Wrestlemania "MVP" if you may. There could be a multitude of challenges leading up to this such as uhh, basketball games and fire contests and three legged race and all the other usual stuff. Just fantastic. The only question is will the WWE give Taker's last match, as you say it will be, to someone like MVP and put him over? The answer is obviously yes, they will give the trouble-free, loyal superstar that privlege.
Bottomline is MVP vs. Taker is definitely happening at WM 28, 100% chance and I can't wait to watch what certainly will be a 6 star match.
