When asked by Siliconera at E3 if it would remaster Dissidia for PS3 as part of the PSP Remaster series, Final Fantasy producer Yoshinori Kitase said: “We have no actual plans. he concept of remastering PSP titles for PS3 is a new idea and initiative from Sony. We have not had enough time to think through and plan our actions.”
No Dissidia PS3 for you, then. At least, not yet anyway.
