Quality of software has little to do with a consoles sucsess, you only need to look at the dreamcast to prove that, I don't know how people got the idea that Nintendo release weak hardware just from the wii alone...
Snes > master system
N64 > PS1
Xbox > GameCube > PS2 > dreamcast(and only a margin between the Xbox and the GameCube)
Xbox 360 > PS3 > wii
wiiu > Xbox 360 > PS3
And if you read all the signs Sony and Microsoft want a slice of that wii pie, smart glass act, all these things will increase system base price if the specs are too high per unit, it makes more sense to do what Nintendo did and rehash one systems specs slightly and sell at a profit for 5-6 years and Sony needs it, A10 is crap APU but their still using it in the ps4, I'd say that keeps the wiiu still up there as the ppc triple core wiiu CPU will outperform an A10, the a10 gets outperformed by i3's in most benchmarks and their older CPUs! Again they all want a slice of the wii pie and will all have an Nintendo inspired control system.
