Nikon D60 - Why?

This is something I do not think I will ever understand. Why did Nikon replace the perfectly good Nikon D40x with a model with almost exactly the same features? In fact its not even an upgrade, the only noteworthy thing about the Nikon D60 is its kit lens, which now includes VR. Maybe its solely because of this that they had to re brand the D40x to a different name. Oh well, hopefully the D90 will be for the D300, what the D80 is for the D200.
