PS3’s sitting on store shelves?

I find this news surprising:  88400 PS3’s were sold in Japan in 2 days

It’s surprising because there were 100,000 units available in Japan.  This means there are ~11600 unsold units in stores in Japan.

Did Sony not manage to sell out in their home turf on opening day?  That’d be a significant statement about the unit’s price point, if so.
