So, Nintendo Is The Only Gaming Company that Can Survive With No Third Party Support? If Not Who Else? (If each Company Had Their Own HW i mean)

Oh God.

Sony and MS could make a very cost effective console that requires no R&D. It will sell maybe 10-20M with zero 3rd party support but it will be sold for a good profit and make money.

That's pretty similar to the Wii U's situation when I think about it.
