Come on b2b. The guy even said "In terms of putting location tracking devices on each unit and having them report back to us--well that's a little difficult." So they don't know either. And we both know Sony didn't launch the number of units that they said they would, and some estimates have been half that.
"We're comfortable we'll have the 400,000 within a week." isn't the same as "We've currently shipped 400,000 this week." and you know it.
So maybe there is the answer everyone's looking for. Maybe Microsoft isn't going to try and speculate how many add-on's they've sold. Maybe they're waiting to get concrete numbers together.
Yeah, Sony hasn't had a problem quoting shipping numbers. They also haven't been right yet.
