[Update] Sometimes things seem just too good to be true. The poster below that shows the PC logo at the bottom indicating that the game would be made available to PC gamers, is in fact an error on behalf of Square Enix. When DuelShockers.com contacted Square Enix to get confirmation of the poster, the company debunked the news,putting it down to design error.
LIGHTNING RETURNS: FINAL FANTASY XIII will be available for the PS3 and Xbox 360 platforms only. The poster ad in question erroneously indicated PC as a platform.
According to a poster spotted in Los Angeles for Lightning Returns: Final Fantasy XIII, the game that is currently only shown as available for the Xbox 360 and PS3 could be available to PC gamers.
The image below shows quite clearly the PC logo (bottom left) which is weird as according to their official site, only the PS3 and 360 are showing as available platforms. With E3 about to kick off tomorrow, it would seem strange that they would advertise this via poster only and not on the official site.
Here is the official E3 teaser trailer for Lightning Returns: Final Fantasy XIII
