There was a Tweet hinting on what champion is getting an Ultimate skin. It would be a champion that has A as the forth letter in his ability. Either Xerath, Skarner or Lux.

Arcane pulse or mana surge

ImpAle

FinAl Spark

Or it could be abilities from a champion that has yet to come up... PS: seriously thinking is Skarner
