If Rafa isn't fully healthy at RG, and Roger ends up defending it..I think he's unstoppable for the CYGS.

I think he now has as good of a shot as he had in 06 and 07. He's less likely to meet and be stopped by Rafa at RG because of all Rafa's troubles imo, though that depends on the draw, but on the other hand Del Potro if healthy poses a threat at RG and probably again at USO. Others like Djoko, Davy, maybe Cilic, can all be dangerous. So I think the field are catching up but then again I didn't expect him to win the AO and he did, dropping only two sets along the way, so who knows if he keeps up the form he's shown this tournament.
Some bookies are giving odds as short as 6/1 of it happening, which imo is too short, but we'll see I guess.
