No. RedRedWine confirmed that we'll be seeing Ultra beasts all the way up to UB-40.

Assuming the player battles them at one point, and that they'realiensextra-dimensional beings summoned by Aether Foundation, I think it's a refreshing addition (to the main series) after 20 years of fighting humans and Pokémon.
I'm curious about how they'd tie into Solgaleo/Lunaala waking up and Team Skull. Lillie/UB-01 appears to be the most important, going by the name alone.
Who is this person and why should we believe them exactly?

Maybe pokemons from another planet? Lol. Technology is very advanced in the pokemon universe anyway they could make contact with life on other planets. Specially that they have access to lots of psychic pokemon to just teleport anyway so it's not like distance is an issue.
Anyway, these are really cool. I WANT to catch them. And we still have 38 more to see? Goodie! I'm very excited about these
