Any early thoughts/predictions on how WM main events 1 & 2 will go?

Night 2 they’ll probably give it to Cody vs. Cena…but where does night 1 main event go? We still have Gunther, Jey, Roman, Punk, Rollins…

MAYBE they’ll do a triple threat w/ Cody vs. Cena vs. Punk? Fatal 4-way adding Roman? Thus leaving Gunther vs. Jey for night 1 main event?
