How come Nintendo doesn't remodel their Consoles until after they're dead?

I think it's cause of the cost. They need to get the prices in manufacturing down first. Than they can pay for the redesign. But that takes a certain time. Though some revisions are released stupid late. GBA Micro, DSi, NES Top Loader, SNES JR, GBA Backlight, GB Light, Wii Mini, New 3DS.
