Is The Xbox 360 Getting A Sega Action Exclusive?

Japanese game maker Sega, perhaps best known for Sonic the Hedgehog and Virtua Fighter, just launched a countdown teaser site for a new game. Possibly, a new Xbox 360 game.

The text on the countdown site itself is thin on details; however, the site's URL (next-360action.sega.jp) has some wondering if SEGA is going to reveal an Xbox 360 exclusive.

Exclusive third party titles have become increasingly rare, and these days exclusive titles are typically published by the platform holders. Many third party exclusives ultimately end up being timed exclusives, though.

If this is an Xbox 360 exclusive, a SEGA action exclusive at that, whatever could it be?
