Why is the Switch still not getting big games from 3rd parties?

You should explain 'special architecture'. Gamecube, Wii and WiiU all used PowerPC, just like Xbox 360 and PS3. They also used normal graphic cards. So... what's special about the architecture?

The Gamecube and Wii didn't use a "normal graphics card".
The Xbox 360 didn't use a "normal graphics card" either.

The Wii U and PS3 GPU's was semi-custom, but were architecturally similar to what was found on the PC.
