I don't think it was a flop, but selling less than half of splatoon 1 first year, and also accounting the fact that there's was almost nothing out when arms came out, to me says there won't be an arms II.
A theoretical arms 2 would struggle to even reach 1.5 million, because this time it won't have the advantages the first game did (having no competition at the time of release).
Bet with Intrinsic:
The Switch will outsell 3DS (based on VGchartz numbers), according to me, while Intrinsic thinks the opposite will hold true. One month avatar control for the loser's avatar.
