Adding across the Sony financials from that time it's about 57 million (hoping I didn't leave out a quarter but I think I got them all). Might be a good estimate of the size of emerging markets to look at the difference. 5 million units over nearly 6 years isn't huge, but given what they try to sell it for there I still think that's a bit surprising.
Primarily an RPG player but have interest in any game that will make me think.
