Seems optimistic, but it is definitely possible (though personally I believe it is improbable). 5 million through the first 6 months of the year is certainly possible (especially if GT5 launches in Others/Americas in June or earlier). Guess we will just have to wait and see.
@ Abcdario: A few days ago you posted in a forum saying that you think the PS3 will top out between 35 and 40 million. Why will it suddenly hit 40 million in Spring 2011?
I'm guessing 40 million will come in September-October, but that's just me.
