Q: Why not Wii / Wii U / PC?
A: Due to shifting production priorities and capabilities of the studio, we don’t currently have plans to release RB4 on the Wii / Wii U / PC simultaneously with Xbox One and PS4. While we genuinely appreciate the support of Wii Rock band users over the years, and the increased interest from PC gamers, the truth is that we had to prioritize opportunities on other platforms with historically larger RB audiences.
Wasn't the Wii a historically larger RB audience than PS3?
