I think the problem with the 3DS's perception concerning if it's a success or failure is Nintendo's insane predictions. Yes, it is disappointing that it's not meeting them, even after they were lowered, but by any other measure (Say, hardware sales) it's doing very well. It's killing it in Japan, and chugging along in the West, and should hopefully get a nice shot in the arm from the huge amount of Nintendo software it's getting this year (And Pokebomb). It's anything but a failure or in any sort of trouble. Now if after all these titles it's still going down YoY, then there is a big problem, but I don't see that happening.
