Bobby Lashley vs Test for the ECW Title
Hardys vs MNM
They may add a women's match, but that has yet to be decided. Basically every other big star is in the Rumble, so those four matches plus the Rumble match itself, which usually is about an hour 10 to an hour 20 should be the entire card.
Interesting note is that on the Rumble poster you have Rey Mystero, who has been out since losing to Chavo Guerrero in an "I Quit" match on a SmackDown a while back. He had some knee surgery, and his return to the ring is pending. They have about 27 guys in the match, so you know that the other three guys will stay a mystery until bell time. Another wrestler that would add a TON of interest to the match would be Hulk Hogan. With a match at Mania in Detroit pending, it would be cool to see the Hulkster make an appearance at the event. Of course he couldn't win, but maybe a couple of eliminations and then him getting thrown out would be great nostalgia for the fans. In checking the roster, the other guy I don't see that is a for sure to be in the match is Kahli. Vince McMahon loves his size, and I can see a Kahli-Undertaker final two with the Taker winning the match.
In one last note, there seems to be a change of venues for the 2007 Survivor Series, which from day one was supposed to take place in Montreal. The venue change now has the event taking place in Miami at the American Airlines Arena. Why is this such a big deal? Well, the SS in Montreal would have been the 10th anniversary of the mega-famous Bret Hart and Shawn Michaels "screwjob" finish. With 2nd generation wrestlers like Harry Smith (the son of the late British Bulldog Davey Boy Smith, who was married to Bret Hart's sister) and Natllie Neidhart (daughter of Hart Foundation member Jim Neidhart, former partner of Bret Hart) in the fold, there was talk of having some sort of storyline with them involved somehow with Michaels and finally a sense of revenge for the Hart Family. Evidently, those plans have been scrapped with the change of the event from Montreal to Miami.
