The 10 million number was for the combined consumer base of Japan, Europe and US. Sony stated they expect to ship 4 million to Japan, 3 million to the US and 3 million to the UK.
I think if they can make the units, they will reach their numbers. But as everyone knows, they are having some serious problems with production.
Anyway, my guess is "yes". They will make the 3 million number for the US by the end of March.
