Not half as many of these people are going to be willing to leave the WWE in the current state of the wrestling industry. With TNA folding (come on guys, it's going to happen) and very little money around in the indys (unless you're a 5 star talent like AJ, Daniels or Low Ki) then you're going to do all you can to stay with Vince.
Even if that means getting involved in a piss-poor pregnancy angle with a botch-superstar and a rookie who is so green he makes apples jealous.
