Well the alternative is them talking about Pokémon Home and Pokémon Sleep again, and I’m not sure I’d survive that boredom.
I'm thinking they'll tease Pearl and Diamond remake. Maybe SW/SH DLC or third entry? And most likely, spin-offs. I do wanna see another Mystery Dungeon, though.
Pokémon Directs have been kept separate from general Directs in the past and usually aren't far removed from them.
Why doesn't it? We still need Pokemon bank info, there's Detective Pikachu 2, and many have been expecting other spinoffs this year.
But they would never announce these remakes so early. Pokemon LG was announced at the end of may for example. Even Sword and Shield have been announced later (mid February). It would be very weird to show these games so early (beside of the fact, that maybe we will not get them anyway in 2020).
