First step might be a console using an ARM cpu, which can push gaming adoption, and then windows proper can follow.
Also - smartphones use ARM cpus and those have been a mature gaming platform for years. I'd say that a mainstream gaming console based on ARM would not change much, just like Xbox 360, PS3, Wii and Wii U did not cause PowerPC to rise in general popularity,
I think gp means a performance-focused console on ARM, not nintendo or mobile.
Not quite. Their last three consoles (Wii, Wii U, and Switch) were about a generation behind their competition, but the first four (NES, SNES, Nintendo 64, and GameCube) were comparable to their rivals.
