According to PWInsider.com, with regards to Shawn Michaels potentially coming out of retirement and working one more match, the ball is said to be completely in his court, as WWE wants him to return for a bout at WrestleMania 30.
Despite WWE teasing friction between HBK, CM Punk and Daniel Bryan on TV during HBK's last few appearances, there is said to be no talk of HBK facing Punk at WrestleMania, or HBK teaming up with anyone to face the team of Punk and Daniel Bryan at the event.
It's being said that if HBK does indeed agree to work one more match, WWE wants it to be a singles match against Daniel Bryan at WrestleMania 30. Additionally, it's being said WWE only wants HBK to wrestle one more match, as opposed to making a "return."
The reason why the company booked the CM Punk/HBK confrontation on Raw this week was so that they could save the Triple H/CM Punk confrontation for later.
Lastly, it's being said that even if HBK decides against returning to the ring for one more match, we can expect to see him a lot more on WWE TV heading into the WrestleMania season.
