So it looks like we were low on FFXIII PS3 and high on FFXIII 360 compared to NPD. We had it at 1.34:1 in favor of ps3, while NPD has it at 1.68:1, a ratio that fits better with both our pre-order numbers and the number of units we've moved at my store.
Our figures:
ps3 - 769.3
360 - 574.6
NPD's figures:
ps3 - 828.2
360 - 493.9
