My understanding is that because of the acquisition of Nokia's hardware division, by Microsoft, they won't be able to put out any new phones till 2017.
Actually no. According to the deal with Microsoft, the non-compete clause expires 31st December 2015. Meaning Nokia can release phones again as of 1st of January 2016. Will they have one released on the 1st January? Highly doubt it. Will they have one out by the end of 2016? Yes.
And yes, it will run Google's version Android.
In 2015 Nokia will be developing stuff for Android and probably putting out a couple more tablets. The N1 is out in China on 7th January and should reach Europe by Summer 2015.
So I'm a Nokia huge fan, I have a WP now because Nokia made a WP. after two years using the OS I started to think that it's really a lost cause! I really like the OS but I am really disappointed with the market share, the app gap and popularity of the OS. And now Nokia is gone, no manufactures seem to have plans for releasing a WP! And Microsoft isn't doing very well! Where is the 925 successor? The 1020 successor? Are they even planing to release any High-end flagship soon? Or they're waiting for Windows 10 which I think would be a disappointment just like WP8! What do you think?
I may not be the most unbiased person here since I've jumped the WP ship the moment Nokia left the phone market and Sony placed the Z3C for sale. And I have absolutely no intention of re-boarding the WP ship (unless Microsoft does a miracle with W10, which is doubtful). However, I understand what you feel as I felt the same for a long time, seeing as me too only got any WP device because it was what ran on Nokia phones.
I don't think WP has a lot of future. Microsoft itself seems to be placing it in the background and Windows 10 will most likely kick it back even further. As I see it, and from what I've gathered from conversations with friends at Microsoft (yes, contrary to popular belief I actually have a lot of friends at Microsoft =P), Windows (Phone) 10 is being seen as an extension of Windows 10 in the meaning that Microsoft's focus is on Windows 10 and not really on a special mobile version of it. They're designing Windows 10 in a way that allows the OS to automatically adapt itself to various screens. That way, they won't spend any more resources into Windows Phone as an OS. They'll focus on Windows 10 and whatever they do on W10, it will have a reflection on WP10. Of course, you won't have full Windows on your phone, but the OS will adapt itself without Microsoft needing a WP-dedicated team on it. Only the firmware will keep coming from a separate team.
So, in a way, WP has no future. When Windows 10 launches, and if Microsoft gets W10 right, then *maybe* you'll see some other OEMs putting out more WP devices. However I expect those OEMs to be mainly PC OEMs like Acer, Asus etc which can offer combos of PC/laptop+phone to make sales more attractive to consumers. Samsung *maybe* join in again. And Lenovo *maybe* release some Motorola phones with WP (depending on how close the relationship with Google will remain). But I don't expect any major mobile OEM to join the WP bandwagon (Sony, LG, etc to join in). HTC may keep re-purposing Android hardware as WP devices if Microsoft keeps lining they hands with silver.
As for the app gap...it's closing. Unfortunately, it's being replaced by what I like to call the "(cr)app gate". Meaning, while WP is getting the official apps, they are either poor ports of their Android versions, web-wrappers, or Betas that are abandoned shortly after release (like, say, Instagram Beta).
You won't be seeing any WP flagship from Microsoft until W10 is released. But HTC is expected to unveil their HTC One M9 in March and perhaps this time they'll present the WP-variant at the same time of the Android one. Last year they said that the Nokia/Microsoft deal was the reason the W8 (or M8 for Windows) was delayed.
