Street Fighter X Tekken producer explains absent Xbox 360 co-op
"Throughout the development process, there are times when new features are added (and we added a lot of them!) and there are also times where we have to make tough decisions regarding things to cut," Ayano said. "This was one of those times. This mode is supported in the PlayStation 3 version, however, since we tackled that earlier and found the architecture of their system to be more conducive to implementing it."
Ayano apologized for the omission, and said that information about further game updates would be "coming up soon."
