According to a Bioware producer, Mass Effect: Andromeda won't be coming to Nintendo Switch

One of the bigger games to launch in 2017 is Mass Effect: Andromeda and it looks like the highly anticipated game will not be coming to the new Nintendo Switch console that was recently announced.
Michael Gamble, the producer behind Mass Effect Andromeda and the Mass Effect Trilogy, has said on Twitter in response to a fan’s question that it will only be available on PlayStation 4, Xbox One, and PC.

This may come as a shocker since the Switch will have some great 3rd party support and one of those companies is EA. We will hear more about why they decided to do this and who knows if it will come later on for the hybrid console.
