Why should 3rd party dev/publishers market and put effort into their games for wiiU?

[generic-user-1]

they shouldnt. the wii u is just no market for the big 3rd party AAA titles.
but that could be the key to nintendos survival. when the gaming market crashes, nintendo can go one like before, whlie sony and ms are dead cuz of no more big AAA 3rdparty games.
