Could see Jericho frustrating Punk again, and then Punk getting his revenge next month.
I'm not sure how long Jericho is signed on for as he did have commitments with his band during the summer. I was under the impression the WWE brought him in to work a story with Punk up to Wrestlemania and then go back to working with Fozzy?
Think he's here until the next PPV is out of the way, and with that being in Punk's home town, would make sense to finish the chapter and see Punk get his revenge.
