Cata itself had the new zones like Hyjal and the like gated off with the "If you don't have Cata, we port you out" spells (which also mis-fired on one quest you were on a mount for, as you snaked into Twilight Highlands)
Phasing limits the world to the point its not really going to be a revamp and, per Blizzard's own stuff as to why we don't have Karabor as a city, hurts server load a bit. So either you've got an expansion you don't need to buy, or they'd have to do something awful like making a whole seperate EK and let me tell you, its bad enough to have two Dalarans, I do not want two Stormwinds and two Orgrimmars
