Has Undertaker written on his page? I think Shawn Michaels will be back at Summerslam, or maybe just after, as they're doing a DX reunion tour in Oct/Nov time. If Undertaker came back now, I think they'd have to throw him straight into something on Smackdown. With Edge injured, Jericho in the Tag picture, they're lacking any depth for the title. It's just Hardy and Punk for the foreseeable future.
