I can see that it is only a demonstration of the planned, and already incorporated, features of Windows 10. There is no intention to release the consumer preview for the public. The first sentence in David's quote, came from that original Terry Myerson's blog, which we all read
"Early in 2015 we’ll introduce the consumer chapter and talk much more about other device types and more consumer features. We’ll then continue the conversation with the developer chapter at our Build conference, and later in the year we’ll release Windows 10 and look forward to some amazing new devices."
We will continue to get the, now, monthly updates until the release.
I am looking forward to the January chat though. At the moment I am still able to do everything on Windows 8 that Windows 10 has offered, so I am hoping to see something more interesting.!!.
