Mini trailer(like the one where runerigus and mr.rime were seen) on 15 June, it lasts 0:56.

We see the dojo and kubfu again, squirtle eating the dynamax soup, beginning to bright red and some dojo students watching this in a surprised way.
We see wild area dens with pokemon as oranguru,tangrowth,bouffalant and zoroark,we see a cutscene where a pack of what seems to be angry black slakoths( probably galarian form) chasing a student near a cave, galarian slowbro walking on the beach, mustard admiring a red apricorn and finally the two gigantamax forms of urshifu roaring during a raid battle.
Then it reminds that IoA will be out on June 17.
