"There’s a deeper story to the character mixing and matching. Daletto has partnered with Kaiyodo, the toy maker response for the Revoltech brand of toys that feature swappable body parts. The characters in Street Fighter Online are meant to be Revoltech models fighting in a digital world. In the real world, Kaiyodo plans on releasing a Revoltech toy line based on the Street Fighter Online characters."
Pretty interesting idea, if a little stupid, I guess. Also, there's two SFO:MG images in there two, but one was in the Famitsu page already. I'd probably get the Ryu one, as I've wanted the Dante Revoltech toy too.
