I dunno why, but I think it would be pretty cool ... have Rey and Edge retain the belts at SummerSlam, Benoit and Angle implode and begin feuding, and Los Guerreros keep pursuing the belts. Edge's character is as a smartass, so leading up to the December PPV have him make smartass remarks about Eddie mowing his lawn (as we've seen on signs) or Chavo working in McDonald's, or their mothers as maids. The fans would laugh and eat it up, and Rey-Rey could do a double-take in the background. Then at the PPV match, Rey turns on Edge, helping Los Guerreros win and re-forming the Latino World Order. He could finally free the Cruiserweight belt from Noble in a heel-vs-heel match, or win from Kidman if Kidman takes it Sunday.
I dunno, I think I'd prefer the LWO over any formation of the Four Horsemen they might be thinking about.
Quite possibly, although vince has shown that no matter what you've done in the past, if you're: A. Talented enough and B. willing to suck up enough then you can still eventually find yourself back in a main even spot in a few years.
