Back in 2012, I had sources tell me about a game that was being considered to be developed by Retro Studios, Star Fox - Metroid: Fusion Saga. It was a title that I learned never reached development, but was pitched. Last month, those same sources told me about another proposed game of Retro Studios’...it being Star Fox: Grand Prix.

Paul Gale Network doesn’t know if this title is indeed in development or has been left on the cutting board, but the rumor does have merit in that the game exists in some capacity.
