Wrestlemania - How would you book things? (**Survivor Series Spoiler**)

How would people book Wrestlemania based on what they know now and what they reckon will happen / would like to see? There is a lot to choose from out there and a lot of titles. Do they include all the titles, do they miss out some big names, will the brands collide?

I am still thinking on how I would like to see things moving forward but wanting to see what other people think
