There seems to be a lot of publicity about Mysterium lately. I think that the communication with public should improve a lot now in general, as they have a new employee who should be taking care about it.
In any case, consider the previous lack of communication and marketing your advantage... thanks to this, Myst is highly undervalued, unlike many over-hyped project which focus on marketing. You can thus buy cheap now and just wait for their promo to start.
