7.5 for the PS3 version and 7.0 for the 360 one... I personally thought FF13 was a 7 overall, and the 8 here represents the improvement.
The embedding should be fixed.
If it's anything like FFXIII... you'll want the PS3 version.
I'm waiting for the US release, but if you're looking to import, get on this now!
The event scenes are completely different from the one that's already out. Microsoft hasn't released this video yet, so all we have to go by is a description of it.
Or a PS4 port.
