So, as some have asked, the answer to the question: "Is Sonic Generations coming to a Nintendo game system," the answer is yes as far as we know. Now, for the Wii? We don't know. It's being assumed a whole other Sonic game will be released for the Wii this year, but there's still a possibility that Sonic Generations will come to the Wii. Most likely not, but there's still a possibility.
Stay tuned for more updates.
