I don't think NIntendo spent any money on this. the game is published by SE in the westDQ almost always sells a lot more on Nintendo platforms than in Sony ones, it's easy for Nintendo get exclusivity of the titles just like Sony with FF. Especially for a 'Monster' title that have always been exclusive to Nintendo hardware. It will probably release in other platforms in 9-12 months like most 3rd party Nintendo exclusives or other platforms will get announced in couple of days/weeks if there is no exclusivity.
