The japanese logo for Pokémon Scarlet & Violet show a blue gem alongside the names - hint to a new mechanic?

Just like X&Y had a DNA strand for Megas, ORAS had the Red and Blue Orbs for Primals, Sun&Moon had Z Crystals for Z moves and Sword&Shield had a symbol that relates to Dynamax in their logos, Scarlet&Violet shows a blue pointy gem alongside their japanese names. What do you guys think/hope this new mechanic will be?
