SQUARE FFXIII: PS3 game quality will not suffer because of 360 port.

[Reasonable]

The quality of GTA IV suffered on the PS3 due to it being ported to X360. Multi-platform titles adversely affects the quality of the game. Time and resources are spent on developing and producing both PS3 and X360 versions of the game. Deadlines have to be met.

 

GTA IV was apparently developed on 360 first (or began on 360 first) as the console was out and devkits were available.  It then came to PS3 later in its development cycle.

 

FF is being developed for PS3 only (according to SE) and will release in Japan first.  Then (i.e. after code is locked for PS3) they will begin 360 port - and PS3 version WW localization.

 

So I really doubt that the 360 port is going to make any impact on PS3 version at this point - considering they've been developing on the PS3 last few years and will finish that version before starting 360 version.
