Hello, I've seen some great artwork created and art concepts you have.
For this reason I had a question in my head, Will there be a collector's edition?
with the art book, a few posters and some figurine or building.

They have always had a digital delux edition with the sound track and a few other things, but they have not made a physical release in the past. Because this is their first published game then there is a chance it will, but it has not been announced that they will.
