C'mon guys, just don't believe this bullcrap. Maybe the person talking is actually hired by Sega, but he definitely is nothing more than a rabid fanboy that is interpreting things he doesn't understand.
NO company in the world would ever say, oh common, let's make great games on two consoles because we prefer those and just accept that we are making a loss, and instead we are financing them with a bad Wii version. NO COMPANY. NEVER.
Also, saying that Wii is only for kids and all Sonic fans own a HD console clearly shows he is completely biased. I haven't been a Sega player myself so maybe I can't judge, but from what I see a good amount of Sega fans have turned to Nintendo now. Also, especially those that loved Sonic would definitely be best fitted at Nintendo's because Sonic is quite close to your classic Nintendo franchises.
