When will DL announce this rollback?

If the terms are only nominally different then I plan to leave DL in later 2024.

Planning a trip to France in early 2024. I’d like to know the rollback details so I know to either to blow a bunch of miles - DL, Flying Blue or Flying Club - for the trip thereby saving a bunch of cash or to fully purchase the ticket thereby advancing status earning MQDs (and MQMs by if DL retains the scheme).
