I think that It will be

World Title
Edge vs Chris Jericho

*i think this jericho/edge fued might happen if edge returns at royal rumble by entering at no 30 and win just how cena won back in 08, and at Elimination Chamber Jericho wins the World Title and Undertaker got robbed basically , so Undertaker goes to raw and beats up cena sayin he wants his title.

WWE TITLE (Main Event)
Undertaker vs Cena

* i think that Undertaker loses his title at Elimination Chamber and drafts himself over to Raw stays there and goes after cena's title .
