Via Twitter, it was announced that Sonic Boom will be arriving in North America on November 11. Why the early access? Most likely due to the fact the game is directed more towards the West, so it would make sense to give the West a sense of early access to the game than the rest of the world. Sonic Boom is an exclusive for the Wii U, so make sure to pick it up!
