According to a Japanese magazine this is true. I think I am the only blogger in the whole world that believed that Street Fighter 4 would be coming to the Wii. According to the official Capcom press site, under platform for SF4, it still stats TBD. A game as far along as SF4, I find it strange that it is still TBD. My hope was that they where still working on a Wii version. I hope we finally find out at the end of may, during Captivity, (Capcom gamers day) if this is true of false.
