I thought the two important teases last night were Cena punching HHH and Punk pinning Del Rio clean. That makes me think that the two matches coming out of summerfest are going to be HHH/Cena and Del Rio/Punk after HHH and Cena get into it during the match, HHH gives Punk the win somehow and Del Rio cashes in.
'course, because that's what they teased, it's probably not what's going to happen.
I think HHH being part of the match hurts it in a major way. He's taking the focus off of Cena and Punk, and turning the whole thing into who he's going to screw. Which is ironic when the whole thing is storyline supposed to be about creating an undisputed champion.
