Alternatively: They're leaving the door open to add additional hardware requirements in the future, like they did with Windows 8.1 and requiring processors had CMPXCHG16b support."Windows 10 is automatically updated. Additional requirements will apply over time for updates."
So, not only does MS not specify how long the free upgrade remains free, it does specifically state that "Additional requirements will apply over time..."
They certainly appear to have left the door open to require a payment, in due time, as an additional requirement for the upgrade.
