i doubt it, vince himself said that it was a one time thing and he isnt planning on giving him another world title reign, the underdog thing is done, and that was the only angle he had to be champ
+ with the main event scene today it would be impossible for him to be champ, like some1 here said b4, with batista, khali and kane as the main eventers there isnt much rey can do, and i can also see mark henry getting in the main event scene soon
so i agree if the contenders were the likes of edge, matt, finlay, and MVP it would be better for rey, they should make guys like khali, batista, kane and mark henry compete for a new title, the super heavyweight title (lol imagine the crap those matches would be...), and keep the WHC main eventers as ppl who can actually wrestle =D
anyways, even with the lack of star power i really doubt vince will push rey again, i see rey getting in the US title picture with matt and MVP though (wich would be awsome)
