Rumor has it that both are retiring but if someone has to lose at Wrestlemainia you can bet your a** it's not gonna be the Undertaker i would like to see a casket match and they both fall in at the same time and when the casket is opened no one is inside but.. that leaves room for more story so what will probably happen is Kane loses in some kind of match and Taker retires being undefated at Wrestlemainia so in hte futre when Taker comes back for a big match at WM some guy can claim to be "the one who beats Taker at WM" but it will never happen
