Wait, it is? That's weird then... Where was that?Lucario is confirmed. However the set says "8 New GX cards" Lucario isn't new
Also, the announcement over at Pokemon.com says "8 Pokémon-GX", nothing about them being new. Still, it probably refers to Palkia and Dialga not being entirely "new" (Crimson did say "8 new Pokémon-GX", yet Ultra Prism just went with "10 Pokémon-GX"; and the latter counted the FA/RR Ultra Beasts and the new Silvally-GX art among those 10, only ignoring the 2 Golden GXs from the total).
