Because gamerfront.de has the same info Shinobi has (y-koron's source), if not better info.
Many times they have shipment sellthrough info as well. Last year, at Christmas, they had all the big release numbers within hours (far more accurately than Shinobi) and % sellthrough first day of titles. They are very good. How they are German, and have the info, beats me, but they do have it.
Back from the dead, I'm afraid.
