At this time, the WWE has no plans on turning Chris Jericho heel. While he played the heel role in Chicago against CM Punk (which the company expected), the company feels that he is one of the most consistent and top faces they have. They also feel that due to his status, he could easily get younger talent over at any time.
Jericho will be with the company until August, and will then go on tour with Fozzy.
