Aye.
Switch is selling amzingly well and in Japan after only two and half years is about to sell more than the ps4 has in its entire lifespan, this means we'll likely be seeing a long life for the Switch and a lot of exciting software that wouldn't have happened otherwise.
As for Pokemon, Pokken DX got ported, Pokemon Quest is free to play, both Let's Go games are a thing and of course Sword and Shield are coming.
Other games that'd be worth your time are Breath of the Wild and Mario Odyssey, Odyssey probably being the best 3D Mario of all time.
Splatoon 2, Fire Emblem Warriors & Three Houses, Hyrule Warriors, Smash Bros, Luigi's Mansion 3, Animal Crossing, Mario Maker 2 and a very healthy eShop selection full of must play indie titles make for a great amount of choice on the system.
There will be more and more Pokemon in the years to come too, Nintendo want at leaat a seven year run with the Switch which is around what the 3DS got and look at how many Pokemon games the 3DS got.
We will easily see at least two generations of Pokemon on Switch, we then have the Let's go series which may endure too and it is likely that remakes of gen 4 will appear on Switch as well.
The Switch is where you need to be so I say go for it.
