What is the lowest realistic expectation for lifetime sales of Wii,PS3,360?

[Darc Requiem]

110 million!? If thats your reasonable minimum sales number RolStoppable, I can't imagine what you actually think the we will sell. As for my reasonable minimum sales. I basically agree with the source, except my PS3 number is 25% lower.

360: 35 million

Wii: 50 million

PS3: 30 million
