Thats possible, worldwide.
In America alone - Spiderman will reach the five million+ by the end of December, I suspect ?!
Its a big success in Europe and Japan too. Thats why.. 10 million units sold are not unrealistic. What do you think guys ?
My speculation is:
If its like 3.0-3,3 million units in the USA alone, and its doing well in europe/japan/rest of world.... its probably over 7m in its first month alone.
Throw in november + december... and yeah it ll be over 10m units sold by end of holidays.
