Why would the Rock want to come back to the wwe to begin with? What about a Rock/Undertaker match to see if he can beat his winning streak?
Probably #1: Vince opened up his vault.
#2: Maybe he's not getting the roles he wants in Hollywood, or he just misses the ring more than he enjoys acting.
He probably figures the window for him to return to WWE is closing due to his age, and he can always go back to acting in the future.
