You keep asking questions that cannot be answered here even if this information was floating around. Sales and special events such as these are never released ahead of time. There is no legitimate way to get this information and since this forum only discuses legitimate information these questions will never be able to be answered here. The only way to get this information is to search elsewhere, perhaps some data miner or hacker has access to this or wait until it shows up in the game. Or start collecting this information yourself to get an estimate of when one might show up.

Locking this as this is another question that cannot be answered.
