On top of this, I think they've made a fatal flaw when it comes to handheld pricing. If you remember, the 3DS launched at $250, tanked hard, and received a whopping 33% price cut only 4 months after it launched, followed by the announcement of the new 2DS which would be even cheaper. One of the things Nintendo produced the 2DS is because they found, to their great surprise, that almost 80% of 3DS customers outside Japan never took their 3DS outside the home. They weren't buying it for portability, like Japanese customers usually did; they were buying it because it was the cheapest way to play videogames, only a third the price of a console and with games that were half the price of console games (in many countries even less). Right now I can buy a 2DS for 105 and brand-new games for 40 where an Xbox One is 400 and games are 80 - 100. That's a big reason many of my friends have one.
Then note that they've also priced the Switch above the iPad Mini. Most handhelds are bought by parents for kids. If parents see that they can get an iPad for less than the price of this new console, they're very likely to: iPads are seen as luxury products with a wider variety of uses and many cheap games, and the iPad Mini is even more portable. This is the first handheld Nintendo have announced since iPads hit the market and I worry they haven't taken this into account.
For those customers, who make up a majority of 3DS customers worldwide, the Switch is a non-starter; it's likely to be considerably more expensive than its rivals, and those rivals happen to have either larger libraries, greater popularity, free online, and better graphics (Xbox One/PS4) or a luxury image, greater portability, lower software costs, and a wider variety of uses including educational uses (iPad Mini). I'm really hoping Nintendo succeeds, because I'm a big fan of theirs, but I worry they have totally killed the big draws to handhelds.
