Seven won't likely die on Jan 14th 2020. Microsoft will stop support for the common folks but the corporate world can still use W7 and get security updates until 2023, but at an increasing cost.
I have a feeling that these security updates will be leaked out with the interwebs being what it is. The much larger issue you'll see from the end of support will be on the software side, Companies will stop making software designed to run on Windows 7, and Windows 7 will go the way of 98, W2K, and XP. (although there are approx 40 million xp pc's still in use)
But on another note.................
More people are still using W7 today (approx 40% ish?) than were using XP back then (29%) and their was so much of an issue with XP when that met E.O.L. that Microsoft had to over extend support. Next Jan will be interesting to say....
Edit: just looked up the market share of W7 and from 5-2018 to 4-2019. Windows 7 leads Windows 10 by .02% That can't be good for Microsoft with only 7 months to EOL of W7
