Yesterday a rumour of a Star Fox racing game cropped up on Reddit and 4chan, which seemed improbable on its own merit. Since then though, Eurogamer, Game Informer, and Kotaku’s Jason Schreier have all claimed they have sources close to Retro Studios suggesting this rumour is, in fact, true.

So the rumour in question concerns Retro Studios, developer of the Metroid Prime trilogy and, more recently, the Donkey Kong Country games. They’re allegedly working on a Star Fox racing game spin-off that is, as the original Reddit leaker DasVergeben puts it, “like Diddy Kong Racing mixed with F-Zero”.

The ties to Diddy Kong Racing arise because there will be a single-player adventure mode with a hub world to explore, events to take part in, and special boss fights. As these races will presumably take place in Arwings, they’re going to be fast-paced and demand lightning quick reactions, as per the F-Zero series. The current name for the project is Star Fox Grand Prix.

Over on Game Informer, they report that they’ve heard Retro and Nintendo have been struggling with an unknown project, and Nintendo has “grown frustrated”. However, Kotaku’s Jason Schreier has claimed this is actually a completely different project, and this Star Fox Grand Prix racing game is on track.

It all ties in very nicely with the Nintendo DS title Star Fox Command. This game had multiple endings, and one of these results in Falco, Fox, Slippy, and co, retiring as pilots and engineering their Arwings into racing machines. “They would enter the high-speed world of G-Zero Grand Prix Racing!”

The sad news about all this is that, if true, it would effectively rule out out the development of three potential Switch games - Star Fox, F-Zero, and Diddy Kong Racing. Still, mustn’t grumble if we’re finally getting a new game from the wizards at Retro Studios.

If we're to hear anything on Star Fox Grand Prix, E3 2018 is the time. Nintendo's Direct video presentation will be taking place on Tuesday, June 12th, at 9am PT / 12pm ET / 5pm BST. For more details on E3 2018, and all the big conferences, head here.
