That is not even remotely the point.

Just because Switch is coming out, doesn't mean that MOST Wii U owners are just automatically going to dump their Wii U in the trash or put it in the closet. In fact, many WON'T be buying a Switch day 1, either because they can't afford it, or aren't sold on it yet.

The point BEING, that there are just about as many Wii U owners out there in the wild, as there are Vita owners. And last I checked, Wii U's eshop was lauded by many indie companies as being a success, as many indie games have done quite well, sales wise, on Wii U. Because a lot of the owners in the install base that IS there, similar to Vita, actually do buy digital indie titles.

That isn't just going to immediately evaporate because Switch launches. And I find it disingenuous for developers, especially ones who had KS funds, and/or hit stretch goals that included Wii U, and thus had a COMMITMENT to releasing their game on Wii U, come up with BS reasons why they're suddenly cancelling the game they already said they would bring to the platform. The fact that the Wii U isn't going to be selling new console units is immaterial, just as it is for Vita. The FACT that does and should matter, is that the install base who is there, has already proven to be fully willing to download and support indie games. Not ALL of them are successes, but that can be said for any platform.

There is no overwhelming reason or excuse why most of these indie devs dropping their games from Wii U, when many of them all but promised they WOULD hit Wii U, and there's no GOOD reason why the console shouldn't continue to at least have a somewhat healthy eShop release slate of smaller indie titles, for the forseeable future.
