Rey Mysterio and Sin Cara vs. Prime Time Players has been officially announced for Raw this coming Monday. Raw is live in Sacramento, California, and has also announced that John Cena will be there.
WWE already has announced Vince McMahon will have a "State of the WWE Address" as well. It looks like the low ratings a week ago are making WWE bring out the big guns for this week.
The other Semi-Final Match in the WWE Tag Team Championship tournament is Cody Rhodes and Damien Sandow vs. Santino Marella and Zack Ryder. This will most likely take place on Smackdown.
