2 Things on this, why is Nintendo held to a different standard than the other two major console makers? They both have released mostly re-hashes, "Backwards Compatible" games, and sequels. No new IPs. Secondly, their price points are up around $400 at launch, but Nintendo has to keep their console to "Around $250" or it won't sell? What is up with the hypocrisy when it comes to Nintendo vs. Xbox and PS4? I really don't understand it.
That being said, I am getting the exact opposite feeling. People are STOKED for this thing. Just for comparison's sake, the Wii U has been out since 2012, right? Looking at the respective views between the Wii U reveal trailer, and the Nintendo Switch reveal trailer the Nintendo Switch is already ahead of the Wii U trailer by almost 10 million views. There is a lot more interest. Not only that, but there are new IPs coming, there is a new Pokemon, new Zelda, new Pikmin, and sure these other games are just modified and upgraded versions of the Wii U versions. But WHO has played the Wii U versions? And WHO in their right mind doesn't like all of these games? I love them, and still play them from time to time. If I can take them on the go, I may play them ALL of the time, who knows?
But yeah, I think the OP is probably worrying about nothing, this system is looking more and more like Nintendo is all in and like it is going to sell gangbusters when it is finally available to the public.
