Will there be any continued support or development of the 2.xx versions? 3.0 seems to be a long way off from being usable in a live environment for me. Besides that, it just doesn't have as friendly of an interface for quick moving around in an improvisational live environment. It seems to be better for creating compositional pieces, but as far as live performance, it's just not as easy to use.
Don't take this as a knock on Bart and Edwin - I still love resolume, and think there are great things being developed. I especially like the idea of using the gpu finally. However, there are still some features I would really like to see in the 2.4x interface however.
