Japan attach rates VGC
360 - 4.1 (due to generally low sales might only pull total down to 6.9)
PS3 2.0 (could pull PS3 total down a few points... maybe to 4.7 from 5.0
Wii - 3.0 (might pull it down to 4.0 from 4.5)
-----------
And although we have no software totals for Others I am sure they would help Wii a little [pull it up to 4.5 again?], help PS3 quite a bit [up to 5.5?], and drop 360 further [probably below 6.5]
So my estimates put it at 4.5, 5.5 and 6.5 for Wii, PS3 and 360 respectively [bundles not included]
