This artcle by Gerry Clarke (aka Yourstrulyinhd) discusses first hand from his opinion who is to blame for Playstation 3's loss of exclusivity with big titles such as Final Fantasy XIII and Devil may Cry 4. And why should Playstation 3 owners/fans even be worried?
Extract from Gerry Clarke's (aka Yourstrulyinhd) article:
I, for one, purchased my Sony PlayStation 3 shortly after its release for $600. Keep in mind that upon release the $600 version of PlayStation was a 60 Gig. An 80 Gig PlayStation was eventually released and the 60 was taken out of production. My PlayStation was not purchased because Sony had exclusive rights to Final Fantasy but because I've always been amazed at Sony's gaming products. I still am. My PlayStation comes in very handy for its extra-gaming uses. Hypothetically speaking, if Square Enix announced after the release of FFXII that the next installment would be an XBOX 360 exclusive I would've still purchased a PS3 for full time usage. It would've sat comfortably next to the 360 that I purchased solely to play FFXIII.
