Samsung's Android 10 beta started earlier this month with the Galaxy S10 series. The software isn't available everywhere, and a wider rollout is expected to commence this week. You can read more about what Android 10-based OneUI 2.0 has in store for users here. Samsung's beta program usually lasts for a month, and a stable build is rolled out a week after. If things go smoothly, we can expect the first OneUI 2.0 builds to roll out as early as mid-November. Ideally, most international unlocked Galaxy S10s should have it before the year ends. Galaxy Note 10 users, on the other hand, may have to wait a bit longer. It won't be long as Samsung Korea posted a hint about the One UI 2.0 beta for Note 10 series today.
