If they offer The Rock as much money as they offered Floyd Mayweather, I don't see how The Rock could refuse. It's obviously about the money. The Rock would of had that itch to return to wrestling normally like all legends do, but he can make so much more money long term as an actor. So if WWE gave him a payday that would be large enough for a single days work to compensate for several weeks worth of filming, the Rock would return. But even if he won't say its about the money, you watch. WWE offers him a big payday and he will come stand and attention.
