What system would you most likely buy Shadow of the Eternals on?

[S.T.A.G.E.]

I loved Eternal Darkness on the cube, but I don't think i'd be getting that next game until much, much, much later on down the road. I will have a Wii U, the PS4 is going to have a lot of exclusives and multiplats when I get it and what exclusives Wii U has that one isn't exactly that high on the list.
