WWE protected Punk/Rock's finish majorly as you may have guessed...

But this could be ridiculously far.

WWE actually hung a curtain around the ring as The Rock/Punk practised the finish/match earlier that afternoon and no one except top officials could see what was happening. 

Speaking of The Rock, he has several movies to promote and will take the WWE title with him to promote it and Wrestlemania along with the WWE. There's no doubt the mainstream attention to the WWE title is something WWE will be interested in.
