The above image shows that the latest iteration of the operating system will arrive as early as December, for the Galaxy Note 5 and the S6 Edge+, as part of the first of three phases in which the updates will be rolled out.
The first phase focuses on the company’s other latest devices such as the Galaxy Note 5, S6 Edge+ , S6, S6 Edge, as well as last year’s devices the Note 4 and Note Edge.

The second phase of updates haven’t been approved yet, although we do believe they will get the updates as the devices aren’t 2 years old yet.
The third phase of updates, will begin after internal testing, and my guess is that these could include devices like the S4 and the Note 3.
