I predict FFXIII-2 will be a major bomb for Square-Enix and will show that the brand is on its way down. They will get the punishment they deserve and hopefully make major losses.
Japanese pre-orders are already pathetic and seeing how overtracked games are in NA pre-orders I wouldn't trust them
My prediction combined PS3 and xbox 360 versions sales
Week 1 Japan,Pre-orders point to 400K opening. 600K Lifetime.
Week 1 NA, I'm saying 300K opening, 650K lifetime
Week 1 EU, I'm saying 350K opening, 700K lifetime.
Overall 1.95 Million combined for both versions combined. We may even see The LAst Story outsell it in the West if marketed correctly.
