That leaves under 5mil to hit 7mil in 8 months of sales. This includes big titles that haven't released yet. We only had BD+Yoshi this year (japan with a DQ remake and Kirby).
Im going to say we'll see minimum 8mil and most 11mil.
We have Japan sales in decline but it has some big sellers coming summer time. US+Europe has big games as well, and we dont kno when the next price drop is (last one was almost 3 years ago)
