Once again, why would WWE have people blade? It's very clear, if they won't have blood in the Hell in a Cell, won't have blood at Wrestlemania at all then people need to get this fixation that blood and blading makes wrestling better. It doesn't. Unless it helps tell the story, it very simply doesn't.
I think Brock is going to win. WWE seem to be showing a weakened side to John Cena, Cena going out and destroying Brock makes Lesnar weak and considering WWE have put a lot of money into Lesnar, having him lose straight off the bat cheapens a lot of stuff they want to do with him in the future. They've not ran these video packages for the past two weeks, building him up to be an "ass-kicker" for nothing. Cena can take the loss and bounce back, it could be used in an angle, something I think they're going for in the first place.
My money is on a Lesnar win after a back-and-forth match. I don't predict blood or any gruesome violence. This is Brock Lesnar vs. John Cena, not Mick Foley vs. Sabu, they're two hard hitting strong brawlers, not weapon wielding maniacs.
