Stephen Elop, CEO of Nokia just announced the Lumia 1520 that we knew was coming from leaks. The 6” display. It includes a 20 Megapixel Pureview camera with optical image stabilization. The 1080p display is the first Windows Phone with that resolution and allows for up to 6 tiles (small) across.
The 1520 can take an expandable memory card (up to 64GB).
