We admit that the first game ever to feature both Sonic and Mario is going to appeal to folks naturally. We don't believe, however, that the game will sell 4 million copies together on the DS and Wii. Sega's corporate director Masanao Maeda believes though.
Being "glass is half-full" kinda people, we're all for being optimistic. But, 4 million? That's kind of absurd, wouldn't you say? Or, regardless of the type of game it is, could any title featuring both Mario and Sonic easily sell that much?
