As posted before, it will release on February 7th, 2020. The set will contain 70 cards, excluding secret rares. Judging by the booster pack, it will feature Rilaboom VMAX, Cinderace VMAX, and Inteleon VMAX.
Nothing else is known about the set at this time.
On December 6th, Japan will get its first Sword and Shield sets: SW1W Sword and SW1H Shield. Each set will feature 60 cards before secret rares. Several of its cards were revealed earlier this week.
As I posted in this theory article, I believe we will get all of the cards from the above sets in our February set. Going forward, I believe the rest of the world will be synced up with Japan’s releases every three months.
