Focus Home Interactive announced the ported version of the game entitled Vampyr into the Nintendo Switch after the game’s release for PC, PlayStation 4 and Xbox One. There is a statement coming from the company during Q3:
In Q3, the Group will continue to maximise the potential of the Vampyr licence. After the game’s impressive success on PC, Xbox One and PS4, it will be Nintendo Switch’s turn to welcome the DontNod title to reach an even wider audience.
The company attempt to widen the audience, as stated on the previous quote. Most likely, they will re-port the game into Switch around October or December, but we still have to wait their confirmation first.
