#1 Retirement match
We all know that this stipulation has the highest possibility of being implemented in the match of these two stalwarts. We know the end of The Undertaker is near, and irrespective of the remorse we feel, delaying this moment would make it much worse for all involved in this situation.
Although an Undertaker win in this scenario isn't impossible. The WWE could shock the whole wrestling community and beyond by "ending" John Cena's career. This would create shockwaves throughout social media and will get people buzzing like crazy. This would allow Cena to focus on his career outside the squared ring and later on, he could make a comeback, as it has been done before by many.
