Well, the way I interpret it all is:
- If there were new features planned for Windows 10 Mobile then surely they'd be in development by now. There have been so few (zero) new features for such a long time that that's the only reasonable conclusion.
- If they were in development then surely a decision would have been made whether or not they'd roll out on Win10M or not.
- Since she wasn't specifically saying just that (that there are new Windows 10 Mobile features coming) I think it's pretty safe to conclude that there actually are NOT any new features coming. A bit disappointing, because it makes it seem like the OS is indeed on a pure maintenance track.
- And since that is the case it pretty much leaves only a couple of options: a) MS is developing a new branch of W10M that won't install on current devices, and that branch gets new features, and/or b) MS is developing for Win 10 on ARM instead, relying on cShell etc to drive the "mobile" experience. The end result is likely the same as "a" for all current device owners in that W10ARM won't run on current devices (I'm guessing), at least not officially. And that in turn leaves a Surface Phone or third party devices running W10ARM.
Either way her answer was really unambiguous. Decisions seem to have been made already and they're not favorable to Windows 10 Mobile Phone specifically. This is almost the opposite of "good news" the way I see it.
The windows insiders teams aren't privy to any long term plans. They are aware of, and work on, immediate short term work.
Hence, they will never be able to give direct answers, to big picture questions unless they are working on something actively for release.
The current work is for FCU, and we already know mobile gets no new features yet (apart from perhaps the HP ones). So nothing said there is particularly surprising.
I mean there's cshell, the paint 3d work, the files on demand work. Its all half done, its there but there's no immediate plan to release it. So whether its being released at some point or not, OF COURSE, the insiders group knows nothing about it.
Me, I think its smart working on bugfixes. If they are going to release new features they SHOULD wait till they have the whole OS running smoothly IMO.
I think there is a few ways that can be read myself, what she did say though
a) Planned features are not specifically win10m. Things like files on demand, cloud clipboard and timeline are all supposed to be android, ios and win10m. So could be that the focus is just now multi-platform there, and they've been told to word things that way, because its supposed to be "inclusive", such as not to push away potential consumers using other mobile OSes. We saw them being VERY careful with this at build - when they demo'd windows 10m running files on demand, they specifically pointed out this would work on other devices. Seems like they are being very careful to try and make android and ios users aware these are not windows features, but mobile features.
b) They are putting Andromeda first. So the current plan is to lead with that SKU, and device, but win10m may follow (or not)
c) There is just no concrete short term plan for any mobile features ATM, just a bunch of vague ones, that the insiders team don't really know whats going to happen with.
I don't see any point much in win10 on arm, on a mobile device, unless the feature can be used without a dock or peripheral.
I don't see the functional purpose in any "reboot" either. Its windows 10 on desktop, win10m on mobile, any additional features or changed features are just new build numbers, not new revisions.
I mean maybe, yeah its a thing they will do WoA some point, and I can see it having its uses, but I don't see it capturing even a small marketshare based on the niche uses for continuum/dex etc. It's likely part of the future, but without unique hardware to utilize it, I don't think is much of a showstopper. Also, they haven't finished cshell. Like most things dev, and msft these days, everything is completed in phases, in multiple roll outs. It's most likely we'd actually see cshell code implemented in desktop and other areas before we'd actually see a fully fledged device using it. We'd at minimum see a demo, like we have with windows on arm.
Myself I am not that fussed on new OS features. I'd like to see timeline, and Cortana skills (part of Cortana), cloud clipboard (part of the swiftkey keyboard on ios and android, and likely part of the new keyboard in windows), and files on demand (part of onedrive). As these are OS wide features, that are partially cloud based, and they are already changing the app based portion for desktop, and changing the keyboard across the platform, I'd be a little surprised if they didn't happen - and they were also promised at build (for android, ios and win10m). The amount of work it would take to bring those to win10m, considering the work is already going into desktop, and the cloud, seems pretty small.
Indeed specifically preventing them from coming to win10m would actually require work - because the new changed apps would need to be modified when running on mobile.
