Please show 'estimated completion date' for pre-order items that are 'in-production'

Hi,  

It will be great if Logos can show the estimate completion date when we pre-order an item, and it says it is 'in-production'.    Many times i pre-order an item, and it says it is in production, and i keep waiting and waiting and have no idea when it will be completed and become available.   I keep struggling to cancel the pre-order and simply buy it on Kindle.     Currently i pre-order a Greek Textbook 'in-production' which i need it in this semester for my class, but again, when i talked to the Logos support, there is no way if it will be available in the next few weeks.    I think it is reasonable to at least give the buyer an estimated time so we can decide whether we should wait (which i do prefer to have it on Logos), or if we cannot wait, we simply get it elsewhere.

Thanks a lot!
