Why are people saying the 3DS is selling badly?

Compare it to Gameboy, Gameboy Color, Gameboy Advance, DS, PSP and any Iphone / Android device and you will see that it sells very badly. This is also the reason why 3rd party support is almost completely lost.

Gameboy/Gameboy Color units are combined at 118m from 1989-2003, which spans 2 seperate generations or about 60m per gen and GBA/PSP each sold about 80m. So a typical successful handheld sells about 60-80m which 3DS will end up doing, DS is the only one that doesnt fit this trend.
