W10 on OTA?

[Mr Question himself]

I heard in WC that 10856 will be the market build to all W10 devices. In fact, 950 and XL will also carry this build but the Q remains, will W10 update for phones be available now in a way similar to how other updates like black, cyan and denim were available? Will it recieve normal OTA update or do we need to get insider builds manually through the app? If it's yes to OTA, when's the official date?
Somebody with the knowledge on this reply smthg!
