I hope you're joking...because if you're serious, that's the most ridiculous and baseless claim I've ever seen. There is NO reason to think that a character, ANY CHARACTER, resulted in this delay, especially since a playable demo was featured at the conference during which Sonic was announced (and Sonic was a fully-playable, fully selectable character, insinuating that he's been done for awhile now).
Most likely, the delay is due to a bug, marketing, or wi-fi related content (such as the "user-created content" that was hinted at in the article announcing the delay).
