Will John Travolta be invited back to announce "Mikhail Keatom" as Best Actor? Will The Academy cave to pressure and just give Selma every award including Best Animation?

Neil Patrick Harris will host this year's Oscars, probably from one of those multi-tiered gold plinths they only have at award ceremonies, taking on the heavy burden of having to follow-up Ellen DeGeneres' world-conquering selfie in 2014.
