Don't hold your breath. Apple has essentially declared optical media dead and they never included a Blu-Ray drive in any of their devices, even the ones that still have optical drives (are there any new ones that do?).
I’ve got a Sony Blu-Ray player, and we watch DVDs and Netflix and Pandora through it.
I’d love to drop it, and use an AppleTV instead, for all those things plus my iTunes library ...
Alas, I think you’re right about Apple abandoning optical drives ...
