does anybody know why the displays are retried and if they will be available in the future? 
:o
Did you really need to scream?
But never heart of it, do you have a link?
You might find a used display or old stock somewhere.
I doubt if any new ones will be made. Who would buy one?
They have a serious design flaw. They are expensive.
They only fit Esplora. Who owns an Esplora? Who would want to buy an Esplora?

They were perfect for small projects for students in our company. So will other displays from Adafruit, for example, work with an Arduino?
Adafruit displays are designed for 5V Arduino.
The small Chinese 160x128 displays are for 3.3V GPIO.
You must decide what you want your students to do.
e.g. plug in a shield and concentrate on software.
or design the level shifters, hardware connections etc ad not worry about the software.

Your company has to decide what you want your students to do. e.g. breadboard or shield.
