Nintendo's success with the Switch both a blessing and a curse?

Switch will start to decline once the new systems are out. However, it not getting as many AAA 3rd party games isn't the only factor to why. It'll mainly be because it is getting older and because Nintendo has already released their big guns. A price cut might slow the decline quite a bit, but it won't stop it.

Naturally, by 2021 the Switch will be 5 years old, every major series will have been out for the system for at least a year already. We can hope it wont be a steep decline.

Why would we hope it's not a steep decline? I like my Switch. But, I would like to see Nintendo move the concept forward. If sales decline quickly, the next generation will come sooner. That's better for gamers.
