Considering that we already know about Sonic Unleashed, Sega has decided to let the hedgehog out of the bag and officially confirm that the game is in development for all of this generation's home consoles and even last generation's just-won't-die Sony PlayStation 2.  So what's changed from last week's leaked information?  Well, among other things, now we know the basic storyline.  Kombo has all the details and a little assumption.

The story tells of the world having been broken apart my the malevolent machinations of the devious Dr. Ivo "Eggman" Robotnik, with the burden falling to Sonic's shoulders to reunite the planet, literally, through the power of the seven Chaos Emeralds. But in order to do so, Sonic will be faced with a new situation that will challenge him "in ways never before seen" (except maybe if you played Twilight Princess -- just a hunch). Day gives way to night and vice-versa, and as it does so, new adventure awaits Sonic across the seven broken continents of the world.

The release states that players will get to engage in Sonic's speed through four new speed mechanics, with combat fighting now possible as well (does that mean a little bit of Brawl may seep through?). "New combat, movement, functional abilities and platforming will be introduced to offer increased depth and variety," said SEGA in the release.

I'd love to see a little bit of Sonic's Super Smash Bros. Brawl talents drip into Unleashed.  The Sonic we see in Brawl has to be the best interpretation of the character in nearly a decade.  I haven't had this much fun with him in years.  As much as I want to see Sonic run, jump, and spin in this new adventure, I wouldn't be opposed to a little kicking and slamming from time to time, too.  In appropriately limited quantities, of course.  The new trailer certainly looks like a return to form for classic Sonic gameplay.  It looks like Sonic Team might get it right this time: no overly radical attitude, no pesky friends, and no out-of-place weaponry; just plenty of blue skies and rapid speed.  On a related note, no sign of Savage Sonic in this announcement.  Perhaps they're saving that for E3...
