Rumor: New Sonic Unleashed Teaser?

It seems as though Sega's new Sonic game, Sonic Unleashed, will end up being leaked in one form or another until the thing is finally released. Though it does seem silly after seeing gameplay video of it, the newest leak of the game is the story teaser. The story is said to involve some sort of "Were-Sonic" type character, and this teaser seems to confirm that, implying a quick transformation as a ring flies through the air. Is it real? It's likely, as the other leaks did end up being real themselves. Whether this is good news or not is another idea altogether. You decide for yourself whether or not emulating the Lord of the Rings camera work is appropriate to a super-speed hedgehog. You decide whether or not the newest Jekyll/Hyde story device is a good use of the license. As for us, we made our decision, if the gameplay is good, who cares about the story?
