New Eeveelution?

So, with every new mainline game that is announced, I feel like new theories crop up about why THIS game will be the one to give us a new eeveelution. So, let's hear it. Why do you think we will get a new eeveelution this time around?

Personally, my theory is that we will get a Steel type eeveelution to balance out Sylveon. In gen 2, we got Espeon and Umbreon, day and night, psychic and dark. Dark is super effective against psychic. Gen 4 gave us Leafeon and Glaceon, summer and winter, grass and ice. Ice is super effective against grass. Steel is super effective against fairy. And I feel it goes with the (little) information we've gotten about the game, specifically about "urban development". Also, they introduced Sylveon in Kalos, so them introducing its pair would fit.

Do I think this will actually happen? No. But one can hope. 😂
