September goes to Playstation, October... is more tricky, especially for NPD.
The Fortnite bundle still counts for September in NPD and the Smash bundle will count for October despite them releasing in October and November respectively.
Due to this I think Nintendo will win October NPD thanks to Smash bundle being counted there but loose WW, looses November NPD since Smash bundle not counted for the month but wins WW, and wins December on all markets due to Smash and Pokémon.
Wow, that is confusing. I naively thought a bundle released in November would count in November's numbers.
