I`m a Nintendo gamer. If their franchises disappeared, i would barely play anything new. There aren`t many 3rd party franchises i like or care about and i don`t know if i`d buy a console just to play them.
I`d probably replay old games and some i never played.
Smartphones were also supposed to put 3DS down and if you look at sales, even if they are less than DS at same point in time, it`s doing very, very well, without signs of losing it`s flame.
Wii U is doing bad for the mistakes Nintendo made. And none of those include mobile gaming.
It`s funny how some claim casuals aren`t loyal but at the same time claim they will never return to Nintendo consoles because of the cheap games... are they loyal or not? To me, not even the core are as loyal as people think. Just look at gaming history.
