Well it wont be simultaneous, but adding up the staggered week 1 launches, I see roughly something like
JP: ~500K
EU: ~2M
NA: ~700K
I love GT5 and it's a day one buy for me, and I know historically the series has sold amazingly well, but I just can't see 10M.
edit: Gonna say 1.5M for EU after looking up prev GTs in the database.
