Keiji Inafune has promised Mighty No. 9 won't see another delay.
Speaking at the Unreal Fest 2015 in Yokohama, via Inside-Games, Inafune said the cause of the delay boils down to the number of release platforms.
He also said should the game prove to be a success, a sequel will be made.
In September, Comcept announced an exact release date for the title: February 9, 2016.
Mighty No. 9 is in development for 3DS, Linux, Mac, PC, PlayStation 3, PS4, Vita, Wii U, Xbox 360 and Xbox One.
Thanks, Nintendo Life.
