hmmm, lets see here.. the wii had poor 3rd party support and the ports it did get was way worse then the others on the HD twins.
however the nintendo 1st party sold stronger then its competitors and software sales are atleast doubled or more. No nintendo does not need EA to survive. If the 1st party is strong enough and nintendo finds their groove with the wii u like they did the wii the cosole will sell pretty strong but not as high as the wii sales did.
i hate seeing people doom nintnedo when they do not reconize the full potentiol the company has. this is no diffrent then the doom threads for 3ds and everyone shit on the 3ds and thought there was no way it could compete to the superior vita and thought the developers would back the vita. Well look at the sales chart and you will have your awnser. Not hating on the vita but hating on hate threads hating on nintendo and all of the hatefullness is hated by all.. so much hate.
WII U // PC // 3ds XL // VITA
