It is far to soon to make any sort of conclusions.
Sony launches in 1 location and all shipments go to that location and hits 1 million. Then Sony gears up for another launch 2 weeks later and concentrates all shipments to that location with small shipments to the initial location. Another 1.1 million sold over those two weeks.
MS launches in 13 locations and distributes the shipments to those locations hits 1 million. Then MS continues to ship to all locations for 1 more week. Likely MS allocated more to US market because of black friday. We just dont know yet. Not to mention they only had 1 week to create and ship more. Likely to hear from MS later this week how many got out.
The key is the are both basically sold-out (Meaning you may find 1 or 2 at some store, but not readily available).
Its libraries that sell systems not a single game.
