If NPD's figures is anything to go by, Star Ocean 4, a game also by Square Enix, performed miserably on the 360, failing to hit the top 20 its first full week on the market.
It's possible considering its install base advantage the 360 version might outsell the PS3 version for North America. But it can also be a major driver for PS3 sales if the 360 version ends up being subpar and/or comes supplied on too many discs.
They feverishly attacked Killzone 2's two days sales for February 2009, but that all seems very premature as well. Killzone 2 for example outperformed Uncharted: Drake's Fortune's first week sales tenfold! And Uncharted turned into a million seller for the US/NA.
It will be interesting, I think FF XIII on the PS3 will easily outsell the 360 version for the rest of the world.
