The spots that the WWE transmited last saturday with the RAW re transmission include some of the programmed roster confirmed right now:
"Heart Break Kid" Shawn Michaels will be there... and no only as a wrestler, he will be in the Arena Monterrey the day that the tickets will start to sell... That's gonna be the Friday 27 Febreaury at 10:00 A.M. ..
The spots (that comes directly from WWE productions) announced also a match with the WWE champ HHH... Jericho, Benoit and the Duddleys has been already announced too..
And...as "a special gift to Mexican Fans from the Smackdown brand.." Rey Misterio will defend the Cruiser Weight Tittle against Chavo Guerrero...
They even did a great spot with Rey, to promote the event, they did it completly in Spanish..! that's great!
I'd seriously doubt that SNME will ever be shown in SNL's timeslot again. The XFL pre-empted SNL's opener when a game went into overtime once and Lorne Michaels apparently lost it, demanding that they cancel the whole television deal.
