Can you explain what you mean by “future buried cards”?
Are you asking about the new and review figures on the main Decks page?
Or on a Deck’s own study page?
Or …?
If you have sibling burying turned on, the main Decks page will show you the full number of available cards (up to your limits) –
–
and the study page will separate out the expected-to-be-suspended-today cards in gray –
.
For Review cards – this count includes cards that are due today (or overdue), but not any cards that are due in the future.
