New Legendary skin?: Battlecast Cho'Gath

Well I don't think this skin will be legendary cause as I recall there is already a legendary Cho skin anyway Gentleman Cho'Gath.I think it or will be in a theme I think a Battlecast theme were you can get Urgot + Battlecast skin + Battlecast Cho'Gath + If you look close in this pic you may see a new Skarner skin?


Any who here is the splash, video and in game 

Cool ins't it!But this is my speculation and my opinion and may not be true!
