>>42139I would say the bigger issue is that early adopters don't always line up with the tastes of the average gamer. For example the Sega Saturn, Dreamcast, PS3 and PSP all had strong launch sales yes quickly lost momentum after early adopters got their systems and the average gamer didn't care that much.
Hell even for hugely successful system like the PS2 the bulk of its userbase came in after it first major price cut and modern Nintendo doesn't do price cuts.
