I think 6m is easily attainable.
I think having it PS3/X360 in US/EUR is a recipe for success. Those that really want FFXIII that can't afford a PS3 can get a $200 360, and the 55+ million install base will make for a strong platform.
I think the PS3 version will certainly beat the 360 version due to >1.5m sales in JP, but sales will be somewhat split outside of that, slightly favoring the PS3 in PAL regions.
PS3 version: 4.5 million
X360 version: 2.5 million
Total: 7 million
Back from the dead, I'm afraid.
