It will be an MK adventure game hes voicing. To be honest I cant see them getting a big name actor in to do random repetitive move triggered quotes. for a fighting game.
I voted narrator but id say either new character, Narrator, or annoncer...He did the voice of the multiplayer announcer in CoD World at War as well as a character in there so he'd fit right at home in MK (maybe the new voice of Raiden would be kind of cool)...
Also you all know he played a Vampire in 24 right...?
It won't be for any of the current cast from MK9, there's no reason for them to change any of their VAs to Kiefer Sutherland. It'll either be someone new or the narrator for sure.
Either that or they'll mod his voice and he'll be the new announcer now that Shao Khan is kaput.
I'm going to say Narrator, he's already done TONS Of voice over work for commercials, documentaries etc so I can actually hear him doing the bios, endings etc
or
Shinnok(possibly) I don't see him as Fujin or another character. COULD be a new character.
