Splitting the update into two parts would have made sense like four or five months ago. Now it would look dumb, and in general might give the impression that I lied or exaggerated in my news updates about the amount of work I've done in all that time. So it would be better to release everything at once. I realize that I miscalculated a lot when I planned the upcoming release, but it's too late to change anything now. So let's keep it the way I originally planned it. This will be a big update, and it will be complete.
Besides, all the rendering work is done, and now I'm working on text, dialogue, sound effects and other stuff.
