Obviously Booker wasn't sent home as he is appearing on Monday Night Raw to face Jerry Lawler tonight. They won't send him home for having TNA stars in his promotion as that's what it is...his promotion. Anyways here's what I see the SummerSlam card looking like:

World Wrestling Entertainment Championship
John Cena (c) vs. Randy Orton

World Heavyweight Championship Match
The Great Khali (c) vs. Batista

Extreme Rules Match for the ECW Championship
John Morrison (c) vs. CM Punk

Loser No Longer Can Call Himself King
Triple H vs. King Booker

Intercontinental Championship
Umaga (c) vs. Carlito vs. Ken Kennedy

Cruiserweight Championship
Hornswoggle (c) vs. Jamie Noble

Rey Mysterio vs. Chavo Guerrero
