Ack, my bad. I was only thinking of comparing it to the GBA ones, I forgot about the 2 massive selling originals on the GB from like a decade ago.
What would make you predict 6 million copies in America? The only original GBA games had attachment of 14% while the GB versions had 20-25% (no successive version have had nearly that high). 6 million American sales would have an assumption of over 40 million DS units in America alone. While the DS is selling amazingly well right now, I have doubts about Diamond/Pearl being able to sell consistently well for the several years needed to get the number you're predicting at with the historical attachment.
Maybe I'm just being a horrible cynic and I'll change my mind once I buy the game this week ;) That being said, with this stock being so volatile and the high price, I see this as a bad place to invest in for the months necessary to determine how sales will go after launch. Better return on investment elsewhere, regardless of which of us is correct.
