Nintendo isn't in competition with Sony or Microsoft, as weird as that maybe be for many here. How is Nintendo competing with itself? That is a better question, and the answer is they're doing undeniably well. The premise of this thread is ridiculous. You're comparing the 3rd year sales of a console that has a well established library/online community to year old hybrid that against all expectations just outsold the Wii's first year.
Making something cheaper doesn't always make it more attractive. Great products and services make it more attractive. Certainly there's been a slump in software output and new reasons for people to go out and pick up a Switch, but Labo is on its way (even if Labo doesn't sell, the marketing blitz will help the Switch as a whole) and E3 is right around the corner, sure to inspire many fence sitters. Oh, and we know Smash and online connectivity are just around the corner as well.
As with many threads, this one's greatest weakness is being too reactionary too quickly. Stay the course, continue to release innovative and imaginative products, and don't get complacent. That should be the mantra of Nintendo.
Finally, the poll results will be skewed. You can't ask a binary question to a group comprised of at least 4 fanbases, particularly when two of those fanbases just about despise each other. There are people who think $99 is too much for a Switch and will always pick "This thing needs a price cut; it's too expensive for what you get."
