In a move that surprised many, it was announced today that Blaster Master Zero will be coming to the Switch at launch. In Japan at least. The game has not been confirmed for the rest of the world yet, but I will remind everyone that the Switch is region free. It is also possible we will hear of a localized version on the Switch this Tuesday at the Nindies showcase.
The Switch launch lineup has grown considerably from what was announced originally. Who knows what will still be announced for launch.
