Seriously, "power" is the least interesting aspect of their new system.
Not considering "power" as critically important is exactly what put Nintendo in the mess they've been in since 2009 when the Wii software sales came to a halt. I don't know how that can ever be
uninteresting, especially in this forum.
If you suggest that "any armchair expert can design a XBox x10" then what I would call ridiculous armchair expert-ism is to repeat the usual taglines like "
what matters is the games" or "
what matters is if I have fun with it", while putting power on the bottom of the list of priorities.
Power will determine if the NX can or cannot play multiplatform games from the other two consoles. Therefore,
Power will be absolutely critical to third-party developer support -> without which no console has
ever been well succeeded in the long term.
Power will determine if Nintendo is willing to risk making fewer money (or even a loss) on selling the console.
Power will determine the price of the console, the necessary cooling (noisy? silent?) and power delivery systems (external brick?), all factors that could sway customers one way or the other.
Power will determine if yields can become a problem which could lead to production and distribution shortages.
Power is absolutely critical for the console, the company's survival and the jobs of tens of thousands of people (not to mention that Nintendo must be a substantial fraction of Japan's GDP, which has been struggling itself).
If Nintendo doesn't find it
interesting, then they're doomed and there's no amount of waggle that will keep them afloat.
