Rol, is correct in the fact the Japanese charts are off significantly for the PS2.
However, overall, yes, the X360 has the highest attach ratio in history at this point in it's lifetime. MS has pretty much had the title on lockdown since it came out. It debuted at 3.9+ units per console @ launch in the US (Wii was at 2.9 sold games, and PS3 at 0.6 for opening week), and has increased it's ratio far quicker.
Last week, in the US, the attach ratio was 20:1. 35k h/w units, and 700k+ s/w units. It'll most likely take the US/NA lifetime crown (at a ratio of 10:1) at some point in the future.
The bad part with such an insane attach ratio is that if the console isn't selling, the point is pretty much moot. Who cares if your system has a 10:1 tier ratio, if you only have 10m systems out there, and everyone else has a 5:1 ratio, but 25m systems?
All that matters is total software sold, moreso than tier rates. Fortunately, the fact is, despite the h/w doing mediocre, software, aside from the attach ratio is just great, and no one can dispute that already SELLING 13m software units this year in the US is far from a bad thing.
Back from the dead, I'm afraid.
