Thanks to Ryan Winfield for sending this in:
Matt Fowler from IGN was covering Comic Con and just posted that CM Punk showed up to the WWE booth and had a confrontation with HHH. He even took Gewirtz to task over not pushing Zack Ryder.
WrestleZone has learned that The Heyman Hustle website had cameras on hand and photos of Punk crashing the event should be available soon. Be sure to check back to the site often for updates.
