"MS might just terminate support for Win7 altogether on the grounds that Win10 is a service pack."
Nonsense. Your hypothesis fits the the business models of Apple and the non-commercial Linux distros.
The updates will come until early 2020. Since not all Windows 7 editions are eligible for the update, namely the Enterprise and Embedded version, those systems would still need people to develop patches.
As is the case with XP, Microsoft will be selling expensive support options for the EOL systems for a year or three after that date.
