Will windows 10.1511 eventually get the anniversary update automatically?

I currently run the Windows 10 professional 1511, which I upgraded to from Windows 7 (the same edition) on July 25th.

I thought it would be a 30 days delay before I get it through the windows update (due to the provided ability to revert to Win7 back).

But now as more than 30 days has passed I still don't get it in the list of updates.

I realise that I may download and install it manually, but the question is whether it would get it automatically eventually or not?

Answer

Yes, you should get it eventually. I have some machines that have gotten it automatically, and some that haven't. Apparently Microsoft is doing a phased rollout:
