They don't really need each other. Booker has all kinds of money saved up and has several succesful businesses in the Houston area. The WWE doesn't need him as he'd simply get lost in the Cena/HHH/Undertaker/Michaels/Y2J/CM Punk shuffle. A deal may get done but neither side will get exactly what they want. Booker will no doubt want a Shawn Michaels/Undertaker deal where he wouldn't have to do many road shows and I don't see the WWE getting anywhere near that point with him. It would set a bad precedent for other mid-to-upper card wrestlers.
