Hmm... ok. Let me ask you. How long have they been working on FFXIII? I bet they understand it much more than the 360. Not to mention they made games for similar systems. PS1, PS2, and PSP. Trust me this not even a valid discussion. Look at it, they have been working on this game long enough where they would already have gotten through over 80% of the problems. Now they have to start over while still working on the PS3 version. It going to be even later, get over it.
