As noted yesterday, sources in Mexico reported that The Undertaker is scheduled for the upcoming WWE tour in Mexico from October 16-18. The tour will include shows in Merida on Friday, October 16th, Mexico City on October 17th and Monterrey on October 18th.
WWE today officially updated their live events section to include 'Taker for all three shows. As of this writing, they have not added 'Taker for any other live events or televised shows.

This is definitely his very last ride, his farewell tour.
Hope they make the most of it before Taker rides off into the sunset after Mania.
I can see Taker beating Brock at SS, then doing this Mexico tour (they might as well do a network special), coming back to wrestle again at Survivor Series (against Sting, perhaps) and then have his retirement match at WM.
