McIntyre will win the World Title within the next 2 years and that is 100% certain.
Morrison won't win the belt anytime soon. Maybe in a few years when the Attitude Era guys are leaving WWE.
Cody Rhodes is about 5 years away from realistically winning the World or WWE title.
Christian will win the title by the end of the year or at least by Wrestlemania 27.
Kofi...no...Sorry
R-Truth...

Miz: Before I thought he would, but now I don't see it happening until at least mid way through 2011 if he does ever win it.
Ted Dibiase will win the title, but that won't happen for about 3 years or so. He still needs to gain some credibility as a Mid-Carder.
Matt Hardy: No, should be but wont ever be.
