I'm guessing in this case the 8m is a "shipped" and not "sold-through" number
[Edit: As confirmed in the post above mine ], but impressive nonetheless. It seems that MS understood the market better than most of us suspected when we said $150 was too expensive for mass market appeal.
I must say I've been recently surprised (ie: the last 2 days) that nearly everything Kinect related is sold out in my local stores (yes, this is a 'personal observation' and I'm in no way assuming the worldwide picture mirrors my local one
) I went out a couple of days ago to pick up Your Shape with some credit I have on my Game storecard. They didn't have a single Kinect game from the big titles (Kinect Sports, Dance Cental, Your Shape, Kinectimals) in stock. A couple of copies of EASports Active and a few copies of Motion Sports.
So I went to HMV, not a single Kinect game in stock. Sainsburys, a single copy of Joyride. Tesco, all sold out, Morrisons, a copy of Joyride, 4 Dance Central (which were gone the next day) and a copy of Kinect Sports. PCWorld, nothing. Gamestation, nothing.
In fact, what struck me the most was how decimated the software sections were for the 360 in all of these stores, much more so than the other consoles. Which leads me to believe that people were buying a lot of Kinect bundles and then picking up some other 360 software as well.
Again, I stress this is local (town of 300K in Middle England) and I am in no way assuming that the situation is mirrored in other towns or countries. It's just that I was genuinely stunned to find so little Kinect
software available.
