No use in further speculating, gents.
We'll have to wait and see. But nothing as drastic as a whole missing environment, I'm quite sure... But those that read well, and between the lines well, have already deducted that some things are most likely not making it in the initial release but will follow later, due to what has been said in other topics and/or has been mentioned by Vstep. Other features might have been adapted further to enhance game performance, etc. In-developement images are always of an unfinished product. And sometimes people forget that.
Yet if such content can be seen again on screenshots that were posted on a gaming site as if they were brand new,even though they include much older ones.. then people might get the wrong idea about what the actual state of the game is at this point.
No more details though, I'm sorry. Just a little while longer and then you can all see it first hand.
