Nokia 2 to be updated directly to Android 8.1 Oreo
Although they are aimed at the entry-level segment Nokia 2 and 3 will be updated to Android Oreo as well. Despite the fact that both pack hardware that in theory might not run Android OS as smooth as a mid-range smartphone, thanks to Android Go, at least one of these devices will have no issues with Oreo.
Obviously, that won't happen until next year, as HMD Global will probably want to release Android Oreo for its other two smartphones first, Nokia 5 and Nokia 6.
