Rumors of the game have been swirling for several months in light of talk from some sources that Retro Studios' title has been struggling, with many at both Retro and Nintendo growing frustrated with the state of the project. Boss fights would presumably get carried out as they already are in Star Fox games themselves with some tweaks to suit the new game, and it would be able to offer the trio of vehicle varieties that game was known for via the Arwing, Landmaster, and Blue Marine. They have released a title since Donkey Kong Country: Tropical Freeze on the Wii U, and since then, and the announcement of the Switch, many wondered what their new game for the new system would be. Which begs the question - why go with the Star Fox branding at all?
The gist of the story is that Retro is designing Star Fox Grand Prix as a racing title, as the name suggests.
It's also a little-known fact that Retro helped out extensively on Mario Kart 7 on the 3DS, and so do have quite a bit of experience making non-simulation-based racing games. A Star Fox racing spin-off.
Diddy Kong Racing, developed by Rare and released for the Nintendo 64 in 1997, was a fantastic title that is often glossed over in Nintendo history.
There's been substantial skepticism of Star Fox Grand Prix by commenters. The Ubisoft developed game has since earned critical and commercial acclaim. And if that's the case, Nintendo is nearly certain to pulled the curtain back on the project at E3 next month.
