I just spoke to a Galaxy support rep, and they gave an ETA of about January/February. I don't know if this is completely legit but if it came from a support rep, I'd think it's true. And the ETA seems legit.
I don't know what you guys think of this but... yea. Hopefully we get the Oreo update. I'd also suggest you speak to support reps yourselfs to comfirm it
