Hello, I have been seeing a lot of fake leaks recently on here and wanted to clarify some of the information. Everything I am saying is fact from time of posting, may change on release date.

New Galarian forms for,
-Dustox
-Slowpoke line
-Jynx line
-Tentacruel
-Lopunny

These are confirmed, not sure anymore yet or the typings for these. In addition a list of items from a datamine got leaked recently, I will explain what they all do.

-Max honey, cooking item. Kind of works like gigantamix as in you are guaranteed a certain rank of curry.
-Max mushrooms, same as above.
-Galarica twig, an evolution item for a new Galarian pokemon.
-Galarica cuff, an evolution item for eevee. There will be a new eeveelution just not sure what type yet.
-style card, allows you to change your trainer’s outfit from anywhere.
-Armor pass, the pass you receive to travel to the isle of armour.
-Exp. Charm, increases the amount of exp you get after battles, does not effect exp from candies.
-Armorite Ore, something relating to armoured mewtwo, not confirmed yet but very likely.
-Mark charm, increases the odds of a wild Pokemon having a mark, a rare type of ribbon a wild Pokemon could have.

That is all the information I have.
