I placed order on Dec 13th 2024, and since now I believed that is over 90 days, and always get replied next batch and next batch.
If you included the cm4 and the 4g it would take a LOT more time than just 3 months. and apparently the black version would also add a month or so so you might want to change it.
that’s okay, everyone goes through it 
Just to add to this, recent posts in the shipping thread indicate that silver takes 1 - 3 months, and black takes 3 - 4 months. The main factor of delay is the CM4.
