Sega is almost definitely announcing a new Daytona USA game in the near future. A newly released teaser video from the publisher invites fans to guess at which "classic SEGA franchise" will be coming back soon in some form. Those who guess correctly have a chance to win a free game by e-mailing the address in the video.
Sega offers a single hint to help you identify which game announcement is one deck, and it's a pretty telling one: a snippet from "The King of Speed (Rolling Start)," by Takenobu Mitsuyoshi, featured on the original arcade game's soundtrack.
So... uhhhhh... yeah. You might want to go ahead and e-mail Sega about that sweepstakes. Daytona USA is pretty much it.
