So this refers just to the branding of Windows, right? Unless they've figured out a way to replace versioning, surely there will still be "versions" to hint at compatibility and mark certain upgrades for the sake of developers.
For sure -- Microsoft needs to keep Windows advancing, but businesses will remain cautious and delay rollouts of major upgrades.
So there will still be major versions, each with their own security patches etc. -- I don't think there's any way around that.
At least this lets Microsoft keep more people up to date and minimize version skew -- "You want to upgrade, we want you to upgrade ... by all means go ahead and upgrade!"
