V16 is due for release next month. It will contain a variety of features to cover both aspects, attracting new users and reacting to feedback from existing users. At this point we are still finalising the marketing material and don't really want to spoil the impact of the launch by pre-announcing the details of the contents. I would expect that you'll see the usual brochure about the new release some time in the next two or three weeks.
V16 is in the final stages of testing at the moment, release is imminent but we don't set an absolute date because we only want to release it when we think it is ready. Once it is finished and released, there will of course be a demo version you can download from the web site to try out.
