LOL? Where did you say it flopped? When you said the most logical thing is to compare it to the NDS. Yes let's do that. 35k vs 400k.... Hm.... by this comparison all we can do is come to the conclusion that it's a flop. Why else would you want to compare it to the DS?
The PS3 and 360 have not been held to the Wii's standards at all. Why do you think the Wii fans always go into threads saying "Yeah but the wii did this!" or "I don't know why you guys exclude wii in these comparisons"
