Sony and Sega are teaming up to skin one beloved icon with the blue spikey exterior of another. According to the pages of PlayStation’s Hong Kong site, costumes for Sonic the Hedgehog, Tails, Knuckles, Werehog and Dr. Eggman will be available in that region on December 17th. We will most likely see them release here in the States as well, but nothing official points to it just yet.
