How long was the development period for Splatoon 2, and how long was it for the original"

Hisashi Nogami: We were doing fundamental technical research as we worked on the updates for Splatoon, so there isn't a clear cut-off point. However, development on Splatoon 2 began in earnest from around October 2015. A straight comparison isn't really possible, but I'd say that the development period was about the same as for the first game"

When the paid online service debuts next year, will it change your approach or how you go about Splatoon multiplayer"
Hisashi Nogami: As announced before the game's launch, our plan is to release updates, including new weapons and stages, for one year and run Splatfests for two years. I can't tell you anything more beyond that at this point.
