Basically it sounds like you can buy the base console for cheap (720p, 30 fps) but the base console which is portable can have cartridge module upgrades plug into it which increase power.
Apparently Microsoft already knows this and it copying the idea already, lol
It's just you guys still didn't get the modular concept, understand that it's possible to increase the console's capacity upgrading the expansion modules. Basically if someone wants the "basic console" it'll play stuff at 720p and 30 fps in its portable form. If they want to play on the TV they can use the expansion module that works as an external egpu with the graphical power of a PS4. If they want something better, Nintendo may release a egpu model for 4K TVs.
Remember that current consoles are going to have different versions and the industry is going down the PC and smartphones' road, where games run at different graphical configurations.
Did you get it now, the modular concept?
The egpus are like cartridges that fit in the portable console.
That sounds fucking awesome honestly, I have some doubts Nintendo would be this bold though.
