The Undertaker is telling Vince McMahon flat out that he's finished and never wants to wrestle again. Obviously Vince will wait until later in the year and try to change his mind, but Vince has told people that in the past he's never believed the Undertaker when he said he was finished and this is the first time Vince actually believes it might end up being true.
Undertaker never wanted a big retirement send off match and once he passed the torch and the streak was broken, he felt no obligation to continue.
As things stand now, Brock Lesnar vs. The Rock is the match Vince really wants for Wrestlemania 33 in Orlando. He's wanted that match before, we'll see if it finally happens. Vince feels like Brock was pretty much wasted this year and is determined to get him into a bigger match next year, especially with all of the money he's being paid.
