Retro Studios has been diligently working on a secret project for at least four and a half years, and they've revealed virtually no hints or clues in all that time. With E3 just a month away, fans are hoping for a big reveal, but the cat may be out of the bag a bit early.

A pretty wild and crazy rumor has been making the rounds lately, as they often do just before E3, but this one might actually have some substance to it. According to various alleged leaks around gaming forums, Retro Studios is working on a Star Fox racing game. What makes this rumor a little more credible is the fact that Eurogamer has stepped forward to state that they've heard similar things from their own sources in the past.

If the leaks are true, it sounds like a more ambitious project than just a standard racer. The game allegedly feels like a cross between F-Zero and Diddy Kong Racing. It's rumored to include a hub world, an adventure mode, and even boss battles, and the title is apparently "Star Fox Grand Prix," although Eurogamer could not corroborate the title. Someone on 4chan claims to have leaked the logo, but Eurogamer isn't vouching for its validity.
