So the Rock IS confirmed for Wrestlemania? I hope he actually stays with the WWE until then, because if he just pops in and out of TV that's not really fair for the people who do work night in and night out and bust their ass but lose their spot to a guy who can just walk onto the biggest show of the year for free.
That said, I'd love a Cena/Rock feud, as I think both are very similar. I've been comparing Cena to The Rock recently, with the catch-moves and promo skills and such, and Rocky would definitely put Cena over.
Of course, having the Rock face Orton could help him too, since he'd be killing another "legend."
But I want Rock vs Cena.
