Right now I'm not sure, so I'll list everything I'm considering.
New releases in 2019:
Yoshi's Crafted World, Fire Emblem: Three Houses, Doom: Eternal, Daemon X Machina, Pokemon Gen 8, Luigi's Mansion 3, Animal Crossing, Travis Strikes Again: No More Heroes, Marvel Ultimate Alliance 3, WarGroove, Shakedown Hawaii.
Ports/physical indies/remakes in 2019:
Final Fantasy IX, Final Fantasy X, Final Fantasy XII, Tales of Vesperia, Grandia 1&2 HD, Panzer Dragoon Remake, New Super Mario Bros U DX, Crash Team Racing.
Games that might make it out in 2019:
Dragon Quest XI, Bayonetta 3, Metroid Prime 4.
So given these aren't all 'must buys' for me, I'd guess I'll be buying a minimum of 15 games on Switch next year, but that the total will likely end up in the 20 to 25 range.
