Going off-topic for a moment:

If companies like Nintendo and Sony want more money they should turn their attention to esports since they're big and still growing. Nintendo may need that until they can get something together, but even then that's only a temporary solution.
Example: You have a lot of people play Super Smash Bros at tournaments today. I stood by for a good 3 years to watch the scene grow. With their 2 games being popular (Super Smash Bros Melee and Super Smash Bros for the Wii U) those can easily be imported to the switch to help boost sales. However, that may not be an option. Nintendo has shown in the past how supportive they are with the competitive scene. There's the 2013 situation when Nintendo tried shutting down the SSB tournament at Evo, and then you have the Wii U community at a rocky start all because of how the director of Smash Bros was trying to sell to an establish community. So this idea in general is probably going towards the invalid side since it's likely that Nintendo won't support it.

Okay, back to the topic:

I think it started with the Switch itself to be honest. The Wii U hasn't been out for that long before the Switch came about. It just feels weird, because consoles usually gets at least about a good 7 years before a new system comes out. I will throw in the benefit of the doubt; PlayStation and Xbox is making updates to their current systems. Still, not much is being said at Nintendo's E3 compared to their competitors. I would like to see what Nintendo can offer in 2018, but I don't want to see it fall. Hopefully, they can find a way to turn things around in their situation.
