Where the hell does this leave Nintendo?
Either they provide a supplementary device to upgrade the NX like the recent patents show or NX is absolutely a platform that involves iterative upgrades.
NX and SCD is designed to be scaleable. If Nintendo makes the SDC patent into a realized product, users can physically connect multiple SCDs to the console.
Here's the SCD patent, but I pasted in 3 more SCDs and drew wires, just for fun.

Each SCD can have one or more "processors". These are assumed to be CPUs, and we don't know if that means an APU with GPU or what.
