I'm also surprised. Indeed, maybe there is little to no advertising/communication about it. And frankly I don't think it's a bad thing for the moment considering alpha will be in 2017, beta in 2018... I'm tired of all these greedy editors/devs that over communicate in pre-alpha stages about their "revolutionary" games, to end up selling unfinished/buggy games. A working game, with smooth and stable gameplay is surely the best advertising. Free open betas should be opportunities for honest devs to test their 99% finished multiplayer game on large scales, and to create real justified hypes. So imo here is the 2nd explanation : the ambient scepticism. Particularly for an ambitious project like this, it simply looks too good to be true. A good example of it : here this guy may over suspecting things, but I must admit he's quite funny, and I can understand him ^^ Even Jean-Christophe Baillie said that it's perfectly normal to have doubts about their game in this interview (at 20:20, the whole interview is very interesting btw).
