Blizzard already revealed the Tier Sets for Warrior, Hunter, Paladin and Warlock for Dragonflight Season 1 previously, as you can see here.
Also with the first Raid Test of Vault of the Incarnates just around the corner, Blizzard now also shows off the Tier Sets for Monk and Priest. We can expect to see the remaining Tier Sets revealing pretty soon, aswell as the Tier Set bonuses associated with them.
