As for windows smartphones:

"For Microsoft with Windows and for our platform it’s [Windows Phone] the wrong place for us to lead."

Myerson further went on to explain:

"If you wanted to reach a lot of phone customers, Windows Phone isn’t the way to do it. If you want to reach a lot of Windows customers, then this is the largest install base of 9 to 30-inch screens.  If you wanted to do new and exciting things, then the Xbox and HoloLens is the place to have a discussion."

In short, it seems like Microsoft doesn’t want to focus on Windows Phone through the year of 2016, instead focusing on refining Windows 10 for other devices, and working on Surface and HoloLens. You shouldn’t completely give up hope, though–Myerson made clear that they do intend on focusing on Windows phone, but 2016 is just not the time. He further commented to The Verge:

"We’re fully committed to that 4-inch screen, there will be a time for it to be our focus, but right now it’s part of the family, but it’s not the core of where I hope to generate developer interest over the next year … We’re going to do some cool things with phones, but this year phones are an important part of our family but not the tip of the spear."

Hopefully they announce the release date for the anniversary update at e3 instead of saying "this summer"
