Currently, the #1 thing I want to see more of is modules. The (formerly?) primary selling point of D&D Next would be how customizable it would be. I understand that they're still in the process of getting a core that they feel comfortable with, but it's been several months now, and we still don't know how they're going to work, let alone how backwards compatibility is going to function across multiple, highly distinct systems. There haven't been many new ideas expressed in D&D Next, and even the good ideas like Advantage have a host of problems that need fixing. I'd really like to see them display the supposed strengths of D&D Next (flexibility, customization, backwards compatibility), rather than have them show me "Generic Fantasy D20 RPG", because right now, D&D Next hasn't showcased any reason for me to change systems.
