Key makes me think GTAV.
You would think multiplats would be largely inconsequential in terms of end of the year sales all things considered, but I think if GTAV DOES end up launching with PS4 and ONE (obviously a next gen version has not been officially announced) with no version on Wii U, that would be seriously damaging to the Wii U in it's most crucial holiday, and possibly Nintendo's most crucial holiday ever.
I think something like GTA is much more likely to get people to jump on board next gen, as opposed to something like CoD, which seems to look the same regardless of gen and depends so largely on multiplayer/existing install base. A Wii U version, despite an obvious graphical difference, would at least ease the pain and offer a viable solution to all the younger people interested in Mario games on top of GTA that can realistically only hope to convince their parents to buy them one new console.
