The release date will depend on how many volunteers help produce content. Production is nearly at a standstill if I am the only contributor.Perhaps you could experiment with actively increasing public involvement around this community, rather than only relying on the promises of a few. What springs to mind: continuing in the spirit of the tiler app, making known highly specific needs on a regular basis, incentivizing to generate raw content. Just a wild idea, but I believe there is much untapped creativity to be found from this site's members.
