Hey, robains​- Great questions. Hand-off can mean a lot of different things. From our conversations with designers ranging from indie to agencies to enterprise, many of them work with developers (not just web developers, but also desktop and native mobile developers) who need visual assets like SVG, PDF, or static images, as well as measurements and a broad sense of what motion is required. XD does provide this, and we're planning to work on a more robust developer hand-off that includes styles, colors, and more. XD is much more than simply prototyping. To give you an idea of where we're going, check out the presentation we did at MAX last year, which talks about our vision for where we want to go with XD. Adobe MAX 2016. Day 1 Keynote (Chapter 3) | Adobe Creative Cloud - YouTube Start around minute 22 for the future of XD. Hope that helps! -Elaine
