NPD for March is 4th through 31st like DKII stated. It'll be a very interesting April, as it'll count a great period for GHII for 360, and 2 weeks or so for SPM. March will be very interesting, as it covers a large # of days for Crackdown, Def Jam Icon, GRAW 2 and the winner, God of War 2.
Back from the dead, I'm afraid.
