Now that's the million dollar question @UpdateOS
Samsung won't typically give info out on future updates I'm afraid.
The advice I was given is to keep checking your phones software update settings in the phone.
It can't harm checking the various blogs and tech sites that discuss such material too.
I'm using an unbranded Samsung Galaxy s8 in the U.k and am on Nougat Android 7.0.
Quietly looking forward to the new O firmware currently in Beta.

Hi I understand the frustration of other devices getting the update before your device
But I'm pretty sure Samsung has one of the biggest portfolios of smartphones on the planet in many different languages
The positive thing about waiting a bit longer is if/when your device gets the update is it will have less bugs to slow your device down
I am also hopefull of an update on my S7 EDGE
