I don't think anyone demands! I think we'll just like to know something. Like how much we're gonna have to wait. For instance i could tell my boss, "listen man, the render engine is not ready yet. and so it's you sss strawberry. I'll get back to you in a week, or in 2 month :D. And so will be my paycheck:D"
that's all. we all understand that the work this guys do, it's very difficult, and i personally am in a great admiration for they'r work. But don't be like nextlimit was. Don't say something and than keep silence when it's not there. This will just annoy users. Tell us, approximately, how long :)
