I've had my 1520 since December 2013 and due an upgrade toward the end of the year. I'm starting wonder if MS are going to take another punt at the high end market or simply continue to build and release low end devices. A quick scan over windows phone news articles over the past couple of months would suggest the lower end market is the one Microsoft are interested in. I appreciate Windows 10 is with us soon and wondered if anyone had heard about a high end windows phone in the works?
