Installation of builds by using the Windows Device Recovery Tool?
I too was thinking it would be something about how it is released. I feel like this would save a lot of time, especially if it combines installation with hard reset.
Installing an image using the WDRT actually IS a hard reset of the device, so, yes, it saves time. However, it doesn't really provide a way forward for how things need to be done AFTER the RTM is released. I would definitely prefer this as an option, but it's probably a bit late for this since we are getting so close to release.
Windows builds will be patches not full update images
This would provide a way forward for how things need to be done after the final release. As close as we are getting, it is very likely. However, I'm not certain it would qualify as something that they have never done with a build before, as it seems this has been done already, though I can't be certain.
I kind of suspect that it will be releasing a synchronized build between PC and Mobile, as that is the ultimate goal to keep all OSes updated to the same version. If that's the case, then this needs to be accomplished at some point soon.
At any rate, it should be around 2 hours from now that we find out the details, if it's 9:00am Pacific Time, that is. Nearly 7:00am Pacific Time now.
