Here is the slide from the Verge livecast [0]. It's followed with this quotation

"Once a device is upgraded to Windows 10, we'll be keeping it current for the supported lifetime for the device."

I'm not sure what they mean by "lifetime for the device", but I think it means you have a year to decide to upgrade to Windows 8, and then it'll be supported for as long as your device is working.

That was my interpretation as well, however, people who build their own computers should probably look in detail what the license entails as it may be like Windows 8 System Builder Edition. AFAIK, the System Builder Edition is bound to your computer's motherboard and any changes will make Windows unusable.
