I'm highly interested in this match for many reasons. Reason number one is because the Royal Rumble is the only pay per view that I order every year. Reason number two is because this match is very unpredictable. When it was first announced, I sighed. I didn't want these two to face each other once again, but I really want to see this match. This match is all about Shawn Michaels. The match result is basically in his hands. For many reasons, John Cena must retain here at the Royal Rumble. First off, the World Heavyweight Championship is passed around like hookers, and it's bad for the title's credibility. We need a guy who can hold the title for a few months, and John Cena is perfect for that.
As NorCal mentioned that at Wrestlemania 25, the HBK vs JBL match doesn't need the title on the line to be a success and a main focus point of Raw. Also, if Randy Orton wins the Royal Rumble, then it makes a lot more sense to have Cena retain here. But if JBL wins the title, then I'm assuming a Smackdown superstar will win the Rumble. The match could actually be decent, I'm not expecting a classic match-up here, but I hope it's decent. HBK is guaranteed to have some involvement here.
I actually think Shawn will attempt help JBL in this match, but it will backfire and lead to Cena accidently winning somehow. Then, JBL and HBK will have a disagreement which will lead to a match at Wrestlemania. I'm almost certain that Michaels and JBL will both be in the Elimination Chamber match at No Way Out. So, for many reasons as stated above, I hope John Cena retains the World Heavyweight Championship so he can go on to face Randy Orton for the title at the big stage.
