Да.
Хотя в оригинале более понятно написано:
To expand upon the eligible time period, we’ve defined a returning player as one who had not logged into Hearthstone for four months as of March 17th, so your last login to Hearthstone needed to be before 11/18/2019 to qualify. If you logged in on or between 11/18/2019 to 3/17/2020, you would not qualify as a returning player and receive the Class Deck.
Т.е. чтобы получить сейчас: ваш последний заход должен был быть до 18 ноября 2019 г.
P.S. Русская версия у нас тоже есть.
