in the end i hope its not delayed

Historically when a game has yet to be shown in playable form, you don't see it on shelves for another 2 years. 2010 makes FF 13 a non factor in this years console sales.

A few notes:

SE has never said that FFXIII would be day-and-date WW. They've alluded to it, and are pushing more and more for it, but never confirmed.

*IF* XIII was going to be delayed due to the Xbox 360, I can assure you that Microsoft would pay whatever costs needed to ensure proper funding for the port/development/translation onto the Xbox 360.

You don't need a full dev team to make a port, since you are just working on the engine, the other elements, like textures, models, videos, are taken from the main branch, probably they will just put an already working team to the 360 port... they are not making another game...

This is what I hope never happens.

It depends on how much money and resources MS gave to SE. If SE is able to higher an additional team to do the porting so the there FF team can do the US/Pal localization then it should receive little to no delays. But i would imagine Q1 2010 release date at the worst.

I guess Japan gets it first... and we get it a year after them...
