Street Fighter x Tekken's latest batch of DLC is headed to PC soon, according to Capcom's Derek Neal.
The DLC takes two forms on the PC platform: Games for Windows Live, and Steam. The Games for Windows Live version is "basically done," Neil said, and he anticipates the release in the next few weeks after the Microsoft certification process. For the Steam version, the Street Fighter x Tekken team is working with Valve "to get all the backend pieces set up," and will submit the DLC for the Microsoft certification process after that is completed.
The DLC on both platforms will be accompanied with a patch that will bring the PC versions into parity with console version 1.06.
