This is kind of backwards. Especially since the USF4's Arcade Hardware is effectively PC based hardware, USF4 runs on the Taito Type X revision 3.
This what is basically under the hood -

Wouldn't it made more sense to work with the Arcade version or PC version of USF4 and do a straight port to PS4 since both the Arcade & PC versions are effectively all using the same architecture, rather then deal with the PowerPC Cell based PS3 and whatever issues that come along with it?
