There will be a new Arcade Model in Japan ( with HDMI and Built-in 256 MB storage capacity ) for about $200, release-date is March 29th.
Maybe that explains the drop ( people waiting for that new model ).
If so, we should see a bump in sales-data in the week of April 4th.
Update: seems its release-date is pushed back a bit to April 5th
