I asked earlier in another thread (too drunk to recall), but when was the last "we've passed the X consoles sold mark" statement from Sony?
I know to keep shareholders happier, they've used the Playstation Family figure, which in terms of overall brand value was strategically brilliant. I'm still curious what the last declared number was. I read all the comments leading up to this post, and I didn't see anything solid.
There was the "Global PS3 sales exceed 360 sales" claim from that research group than ended up being a little less reliable than expected, and Sony hasn't followed up with a PR blast playing up that landmark. I wasn't able to take that at face value because of the methodology from that company (again, too drunk to look up), but I pretty much assume it was accurate. As big as the US market is, enough regions have PS3 as a bigger seller that I assume it's the case. That said, I can't think of a single reason Sony wouldn't have trumpeted that from the heavens the second it happened, especially as a follow-up to their earlier PR about the generation being a marathon, not a foot-race.
They announced they had passed 70 million on 16th of November last year. MS announced the same at the end of September last year (i think?).
