Is it bad if I hope the zeitgeist of Shenzhen gets its hands on one of these and clones it part-for-part? It's likely the only way I'll ever be able to own one, given Nintendo's likely production run.
Nintendo will always be the only one who can legally sell a finished product like that.
A random collection of parts can be made to run a random collection of games at "decent" fidelity+speed, but you get much better results by cloning the output of a megacorp's QA pipeline.
I'd much rather give Nintendo my money for the work they did designing the system, if they'll let me. But if they won't, their design will still likely be better, such that the best third-party device to get will be the one that most closely rips it off.
So I wouldn't be too hopeful for a decent clone.
If you want Nintendo build quality you can buy a Wii (dirt cheap) and a classic controller and set it up to run homebrew.
