If Mysterio thinks it's time to call it quits, then I hope that his Wrestlemania match against Sin Cara (assuming they have it at WM29) is his farewell, and passing of the torch kind of deal.
Would be cool. I'd rather see it happen at Summerslam though. Not the biggest stage of them all, but they could focus more on the match and the retirement, put it higher on the card and give them some time.
