Zelda into Mario Kart into Arms into Splatoon and by then we're at E3. Toss in a few indies, downloadable (Snipper Clips), and assume that literally no other 3rd party games come out for it and I'd hardly call that a drought.
The problem with these types of lists as it assumes people are all interested in all the games. Droughts are personal things, more than objective except for truly bad launches that have no well regarded games releaseing for long stretches.
For me, I could play Zelda on Wii U, don't care much for Mario Kart, have zero interest in Arms, and I got plenty burnt out on Splatoon and I'm not sure there's enough new to revive my interest (I'm mostly just done with MP games period). Also not interested at all in Snipperclips. Only indie that would be appealing is Issac, but I already have Afterbirth on PS4 and don't care about portability at all so no reason to rebuy vs. just paying to the + expansion there.
I'm not saying it's worse than other recent launches. I had a PS4 preordered for months an canceled that a couple weeks out just like I did my Switch preorder for the same reason. Just too long of a personal drought, and nothing exclusive that I wanted to play near launch.
Switch has games. Wii U did not. They can't even keep 3DS on the shelf and you're telling me their new flagship portable will be easy to find day one? Baloney.
I suspect it will be hard to find the first month, maybe two, but pretty easy there after. Much like the PS4.
If this is meant to be a flagship portable they're in trouble though given the 3DS and Vita failed at $250 and this is $300 and a lot of the portable crowd doesn't game on TV and may not see any value in the dock features. Only time wil tell of course.
