There’s a rumor going around the internet claiming that Sonic will make an appearance in Super Mario Galaxy 2.

According to a trusted source close to Nintendo magazine NGamer, Sega’s infamous hedgehog will be in the Green Hill Galaxy level. Maybe from a trusted source, but for now it’s just a rumor. That is until Nintendo or Sega actually confirms it.

With Sonic 4 now officially revealed, and now a rumored appearance in SMG2, seems as if Sonic is gonna be busy in 2010, which is great news to hear.
