No idea where these rumors originated but they are incorrect. Microsoft has already officially announced that Office 2019 will be available as standalone product in addition to the Office 365 subscription model. If you want to upgrade from Office 2016 to Office 2019 you will obviously have to purchase a new license though.
@jaybar, there are several advantages to both, Office 2016 standalone as well as Office 365.
Office 2016 standalone:
- one-time purchase you can use as long as you want (or as long as Microsoft keeps its activation servers up and running, see Office 2011).
- Much cheaper in the long run if you don't suffer from featuritis and don't NEED the latest and greatest the same day it was released. The break-even between purchase and subscription is somewhere between 3-5 years.
- Perpetual license you can resell if you end up not needing it anymore.
- Even after breaking even you wills till have full access to your documents whereas with Office 365 you are limited to read-only access once you stop paying.
Office 365:
- Much lower initial investment.
- Includes all feature updates within one series. In other words: Office 2016 obtained through an Office 365 subscription has been upgraded since release and received new features that Office 2016 standalone has not received.
- Includes upgrades to future releases - once Office 2019 is released there is no additional payment required to upgrade.
- Depending on subscription up to 5 installations on 5 Macs/PCs, Office 2016 standalone is always either Win or Mac and only up to two of your own (!) computers.
- 1TB OneDrive storage - even if you don't need Cloud storage it's perfect as additional backup tier for off-site backups.
- Free minutes for international phone calls on Skype
Those are, in short, the advantages. As much as I personally hate and loathe (for lack of a stronger word) software subscription models there are two that are definitely worth their money: Office 365 and the Adobe Photography Plan, both at around $10 per month each. I did, however, opt for an Office 2016 standalone license instead of Office 365 and would have also purchased Photoshop and Lightroom if Adobe was still selling standalone licenses thereof.
