Ok for the people that are saying that the 360 caused a year delay in FF, I think you need to use a little more reading comprehension. First and formost, he never says that the 360 caused a delay. Instead he says getting both games to equal levels caused a delay.
If anyone has every followed 360 and PS3 development for most games know that the 360 version is always the fastest to get up and running due to better tools, resources from MS and the API. Yoshinori already stated that it took year and six months just to convert the PS2 version to the PS3. Its also not hard to believe that the 360 was already in development before the PS3 Hardware released.
Decisions to go multiplat just do not happen overnight. I am sure the team was working on both platforms well before they informed the public.
While PS3 fanboys will always cry about the 360 version causing delay this or that, but in reality it makes sense for Square/Enix to go multi platform for a game that probably is costing the company huge amounts of cash. The PS3 install base is not big enough to keep the company comfortable in the black so they can make their next games.
