If Nintendo wants Splatoon to be a new AA core series, then I expect no less than a million sales with aggressive marketing and price cuts in the future.

If Nintendo continues their usual marketing for games that aren't Smash, Pokemon, Mario, and etc, then less than 500k ltd.

Between 500K and 700K by years end.

19 Duoquinquogintatrecentillion.

750k by year's end!

Too many variables. Will it release before or after E3? WIll there be good marketing for it? If everything works out, I'd say 300k week 1, 1m end of 2015, and 1.5m-2m lifetime

One zillion copies

Cane we predict Metacritic scores too? I´ll say 84 -87

600k by years end

This game can go either way. If Nintendo advertises it like a competitive shooter similar to TF2 then we are looking at 1M by the end of 2015 easily. If Nintendo just let it sit there by itself 400k.

500k Lifetime.
