Public interest waned such that literary and technical support was difficult to obtain, and keep. Lots of people would immediately say "hell yeah, let's do this!" but when it came to telling those people "ok then, let's get to work", many just... couldn't or didn't find the time.
It's an extremely daunting task, one that Artelevision and Halx managed to pull off the first time through the help of many talented individuals. It was a huge undertaking, but the reward was great. The second time around, the project was simply too huge for the lowered number of people working on it.
Tilted Magazine was great, but the sheer number of available/reliable talents required to get such a monster off the ground is simply not possible to secure at this time. If it's possible to do so in the future, Halx will make the announcement- though don't go holding your breath.
