Prospectors is one of the most hyped game project and has a significant community waiting for the launch. In fact that should have happened, already by end of February, when the closed alpha should have finished.
The fact that the article is titles part 1 indicates to me, that it might be a longer wait, until a release.
Might be, that they will loose their first mover advantage to Itam, whose Gangster arena, should be in soon as well:
