I tell you when. After Battlefield 4 release (trolololo). Just have a patience. BeamNG Dev team tells you about release in Blog or forum.
Why are you putting a sad smiley there? It should be a happy one, because when the devs haven't released anything in a while, it means they are working hard and there will be many new things and improvements coming
I think, I am not sure but I think they have stuff to do outside BeamNG. Maybe they have a job and they have BeamNG as a little extra income but I am not sure about that.
Id rather the developer work on the game than burn time updating me on their progress. I trust they are working hard on the next update and it will kick butt! Cant wait for it!
I suspect a German in their ranks is keeping them on time you know how good the Germans are with their engineering and their coding they are the best around
