SEGA filed trademarks for Ecco the Dolphin, which could mean a new game in a storied franchise that ended abruptly 25 years ...

As Ecco, you are the only dolphin which managed to escape from ... and meet the mystical Asterite in order to defeat the vortex queen.

Trademark renewals don't always mean anything, but fresh registrations relating to the classic Ecco the Dolphin series have brought fans back from the dead with hopes they may be tied to a new game.
