Exciting times !
Meanwhile I've been working already on the Viacoin new features in private.
I like programming too much to wait!
However the roadmap will be later anyways since investors & miners deserve to know the next steps.
Sounds like a solid plan. I feel like you should also work on advertising once you have a better idea of what you want to do. Sure many people know who you are already but there are lots more that don't. Once you feel like you have a solid foundation and understand where you want this project to head use the current VIA twitter, etc to reach out to people. Social media has a huge draw and it could be a game changer for you.
