This should 'help':
Being a PlayStation mag, the publication also naturally asked the duo how the shift to a multiplatform release would affect FFXIII's quality. Kitase was quick to reiterate what Yoichi Wada had been saying since E3: "...the team is looking to specialize it for the PS3 so that the game will be maximized [for that console], and then they will port it over to the 360 and utilize the capabilities of that console." That means no loss of quality.
