5: John Cena proposes Nikki Bella  

John Cena and Nikki Bella will be teaming up to face Miz and Maryse at the pay-per-view. The feud has been a personal one so far and it has exceeded expectations as mentioned earlier. WWE pushed the limits on most of the segments and this resulted in some great story telling.

The relationship between Cena and Nikki was the major plot driver throughout the storyline and WWE could cap it off at WrestleMania. After the match, if Cena proposes Nikki, it would be a major headline-maker. And considering how the storyline went, it would be the perfect climax for the feud as well.
