Sonic Colors will be released in Japan on November 18th for both DS and Wii. There has also been a pre-order items for Japan announced and its a tie in item with the kids arcade card game Rekishi Taisen Gettenka.
That is right, a awesome looking holographic card is what you get if you pre-order the game. The card has Utsuke Nobunaga and Sonic. If you use the card in the game, it will summon Sonic to use. Pretty neat.
