Total DS SW Shipped When It Stops Selling: 600m - 750m
Life Time Estimates for Wii:
HW ~ Unknown but at least 60m by the time things are said and done
SW: HW Ratio at least 6.5 given that Wii has at least 15 million sellers yet to come (GHIV, Wii Sports Resort, Wii Music, Rockband 2, Red Steel 2, Pikmin 3, Animal Crossing Wii, MySims Kingdom, Monster Hunter 3, Final Fantasy: Crystal Chronicles, Mario Party 10, Sonic & The Black Knight, Zelda Wii, Rayman 3 the inevitable good sword play Motion-plus game, the inevitable good Star Wars Motion-plus game, the inevitable good Motion-plus boxing game, etc).
Guess: Final SW: HW ratio ~ 8.5-10
HW ~ 15m-25m J, 30m-60m A, 40-70m O
HW ~ 85m-155m
Total SW ~ 720m-1555m
