Gamasutra NPD: PSP Go, Arcade, Elite, 120GB, 250GB sales shown.

I'm surprised by how much of the 360's sales are made up by the Arcade. This seems to indicate that the 360 is at a later stage of its life than the PS3 or Wii, which could spell trouble for MS from 2011 onwards (or even mid-late 2010, unless Natal is massive)
