A new trademark got filed by Nintendo, Creatures and Game Freak. And it's called VMAX Climax (VMAXクライマックス).
Falls under Class 28 - Games, toys and playthings, where the TCG also falls under.
What will it be for? Maybe a new set name that indicates this cycle with VMAX cards is ending/changing later this year in 2021, and continuing into the 3rd (and possibly the final) year of the Sword & Shield TCG series. Similar to a High Class Pack set, like Best of XY, Tag All Stars etc. It sounds like it. Time will tell.
