FFXIV will launch in 2010 in the same year as FFXIII and FF Versus XIII. For some reason I do not see it happening unless it is a FFXIV launch on PS3 in Japan in 2010. Then it could be true. But worldwide launch of FFXIV in 2010 I doubt it. Releasing all three games in a short period would take away much needed sales of the game.
In regards to PS3 console exclusivity of FFXIV it could be a timed exclusive.
