Ambrose teaming up with Bray Wyatt is unlikely. Ambrose is too much of a rebel to stay under someone's command, and his mental instability should only make it harder to convert him into a sheep. What happens if Ambrose joins Bray? He outclasses his master in wrestling, attitude, mic skills, crowd reaction- everything. Not gonna work.
What I think will happen is Ambrose whoops Wyatt's hillbilly preacher ass so badly that he will have to take a break again; on the other side, Cena put Rollins through a table with the Attitude Adjustment of doom, and move on to face Lesnar at Royal Rumble. After their match, Rollins will try to cash in his MITB briefcase, but Ambrose will interfere, costing Rollins his opportunity and his briefcase.
