Batista in 2014

If Batista had gotten the desired response for winning the 2014 Royal Rumble, was he supposed to have won the WWE Championship and stayed in the company for longer than he did?  

Yup, he cut things short after the Evolution reunion bit and left early.  Originally Vince was going to go all the way with him and he was going to drop the title to Lesnar at Summerslam if I remember correctly.  Regardless of who ended up with it, it was always going to Brock by Summerslam anyway.
