Honestly the biggest barrier is nintendo's policy of making profit on hardware. Microsoft loses $100-$200 per console and the XSX still costs $500. Is nintendo really ready to charge $600 or even $700 for a console that matches what was released 3 years ago? 4 probably by launch?
The biggest barrier is that Nvidia has shown no capability to make a CPU that isn't unconditional dogshit for gaming, and the CPU is the Switch's problem.
The only company that's made an ARM CPU remotely interesting is Apple.
