The current plan is to have him face Daniel Bryan with 'Taker playing the heel. The other scenario is for 'Taker to face Brock Lesnar but that all depends on whether they agree to face each other or not.
A interesting thing is that The Undertaker specifically mentioned Daniel Bryan as a potential opponent.
If The Undertaker vs. Daniel Bryan match happens at WM 30, could this be the end of the streak?
