If they go tri-platform, then I hope the Wii version also get splits-screen as well as solid (even if slightly less than 360) online.
The Wiimote is great for split-screen FPS but so far Red Steel is the only game (I know of) to use it. We kept that sub-par game around for the longest time just for that feature alone.
While I may be bias here, I'd love to see them make this game the antithesis of all other FPS out there. Not taking itself too seriously, playing off a lot of the conventions of FPS, including split-screen and being on the Wii instead of PS3/360. I think if it's done like that, they it'll be very popular on Wii even for PS3/360 fans - and lets face it, a large percentage of them have a Wii.
Otherwise if it's on all three, Wii sales will probably be lacking as multi-console owners will likely get the HD version instead, although some may get both versions if split-screen action is solid/fun enough.
