That's clockwork. The bars on either side are the weights, as you'd see in a grandfather clock. What that has to do with anything is anybody's guess.
Yeah, those are definitely the gears and weights of a clock, so right now I would guess some sort of time management game. At least until the next clue, when I'll probably completely change my guess. ;-)
I guess it's another puzzle game with gears and weights. Maybe it's to connect something to weights and gears to make the clock works.
I see gears...maybe it's Gears of War? Seriously though: A Bobby Carrot action/adventure, ala LoZ? Already got the environmental puzzles down, add some action gameplay and...GOLD!
I think it's a castlevania side scrolling adventure action game. It looks like the character is wall jumping between the gears. Our some type of mini game that's along the same lines, but I would doubt this would be a BIG anouncement if lacked depth
next hint: monday I´ll regularly check this thread. The forum member with the best guess (before we reveal the full story) will receive a promo code when the game hits the store.
