I would think PS3 would have to be at least #2 or 3. Also, where is the Saturn? Sony screwed them with an early price cut (I think before they launched it in Japan not 100% sure), and they launched it early thinking it would help (ended up pissing some 3rd party developers off). You could list any of the extremely failed consoles like N-Gage or Virtual Boy but I guess that would be too easy?
