been hearing that for years now but nintendo right now is in a much better situation than sega ever was when they went under.
first of all, sega lost so much money on failed peripherals, advertising, and back to back failed consoles.
nintendo failed with the wii u but they didn't lose any money on selling the console. they also had the 3ds doing really well for them.
and the generation before that both the wii and ds did really well for them. but they are in a tough spot now thats for sure.
as for games, both wii u and dc have fantastic games. the dc problem was that the ps2 had a dvd player and became more successful because of that. the wii u problems was the lack of 3rd party games.
