I'm less optimistic, I think this is literally their last flagship. The flagship before this was what, almost 3 years ago? Honestly it isn't rocket science, and I don't even work for MS. Finish Astoria so you have access to thousands of apps, and finally put that app gap argument to rest. That's it, that would solve their issues, with all the other stuff it has going for it we would most likely see a large resurgence for them. Microsofts main concern is the cloud and subscriptions anyway. While they hamstrung OneDrive, it's still the best value when you add in Office. As long as they can get on all the platforms to sell their subs/cloud services. I'm not sure why they even bother to half ass windows phone, it's not like they really need it, but I suppose it's necessary so they don't totally get eaten up by iOS and Android, not only in the mobile space but even in the desktop space with things like Chrome.
