I believe that is still Intel's plan.

However, as happens often, people are confusing UEFI and Secure Boot.
UEFI is a replacement for the ages-old BIOS - Secure Boot is an
extension to UEFI to create a "trusted" (for whatever that may mean)
boot chain to get to the OS.  You can have UEFI without having Secure
Boot enabled (that's what I do on my systems).
