This is more of a guess, but if I were a betting man, I’d say Olaf a Frozen Adventure will be an ABC prime-time special similar to what the network has done with Toy Story and other networks have done with their respective animated franchises. I doubt they go the Frozen Fever route in front of a major motion picture as comparison. Also, don’t be surprised if this special also gets plays on Disney Channel.
