Do you expect the 360 to achieve at least 40 million WW sales?

[Reasonable]

I think it'll make 40 M WW, although as Godot says a lot will likely depend on whether it can keep itself in the game in Europe or get squeezed out by PS3/Wii which would probably just rob it of 40 M if it happened.

Of course if they can drive additional sales via lower price points then I could see it hitting 50 to 60 M but a lot will depend on how well PS3 is doing vs it at that point.
