Sonic Chronicles: The Dark Brotherhood is likely to do just as well. Sonic Unleashed - out in November - is another high-profile, high-cost multiformat outing. The 20th birthday party went wrong, but SEGA Superstars Tennis wears the hedgehog proudly, Sonic and the Secret Rings sells strongly, and Mario & Sonic yoyos up and down the top ten even now - as Nintendo's DVD burners work their little lasers off just to meet demand. Sonic hasn't been himself lately, but SEGA will never give up.
