The announcement of this year's Call of Dutys is suspected behind these boxes. The streamers and content creators are only allowed to open them on Monday.
We will not find out what is in the black wooden boxes until Monday, because only then can the content creators open them. A cover letter explains to them that they will not receive the code for the combination lock until August 10, 2020 when you write a message to a specific number.
Since there is currently nothing for Modern Warfare and Warzone after the start of the 5th season about which such a big secret can be made, it stands to reason that it is the announcement of Call of Duty: Black Ops Cold War.
Two boxes are currently known. One went to the CoD news page CharlieIntelthe other to the Streamers Hayashii.
Both of them can handle the box first on August 10, 2020 at 6:00 p.m. German time open, only then we find out whether it is related to Black Ops Cold War. It's about time for an announcement, about two weeks ago a chip bag revealed the release period.
Maybe Activision has also reported enough about the Leaks about CharlieIntel and they find a horse's head in the box – a classic. What Hayashii got into debt is not known.
in the Reddit some joke that it will probably be the next Warzone patch that will now be delivered on hard drives or Activision is now introducing loot boxes and not doing anything by halves.
Whatever is in the boxes, we won't find out until next Monday.
