I would expect them to be released on Monday, but a few players from sections other than my own have told me they heard it will be later in the week. I'd still expect them earlier than later though.
And this is important in many sections as teams may begin playing their 2017 season right away in January, so teams are forming now and recruiting is taking place. In fact, in my area (Pacific Northwest, Northwest Washington) our team forms are due in one week, so even if ratings are out on Monday we don't even have a full week to make sure a team can be fielded, and those players bumped up or down may be in hot demand or have to find a new team to play with.
Stay tuned to this blog or the NTRP Ratings Facebook page as I'll announce as soon as I hear/see ratings are out and follow that up with a variety of analysis on the year-end ratings and what we can tell from them.
