I'm betting this is a downloadable title for 360 and PS3 bound for North America too. Hopefully it's a straight port of the model 2 original and not based on the Saturn or DC versions, even though neither is bad for their time. Mark my words, it's coming! Daytonaaaaaaaa!
"The website of Australia's ratings board reveals that Sega has sought classification for Daytona USA, suggesting the much-loved racing game, first released in 1993, is bound for modern consoles. The classification listing suggests the game is in development for multiple platforms. We've sought comment from Sega."
