Brock Lesnar-WWE New Dial!: Who will he face??

Unsurprisingly, Brock Lesnar has been offered a new deal by WWE. If he signs, and from talking to people it appears there's a good chance he will (millions of dollars for very few dates per year), the big matches being talked about for 2013 are Brock vs. CM Punk and Brock vs. Randy Orton. Brock vs. Orton had been discussed for last year but plans change.
