Next EP will have horses, unicorns, fairies and imaginary friends?

Actually, a few months ago when they showed concept art pictures of new worlds and build/buy, there were these two rooms, a kitchen and a bedroom, with ranch style furniture. We know the world was San Sequoia, but we still don’t know what the other pictures were.
If the next EP is about horses, it explains those pictures.

Also I personally want horses, so I’m glad if we get them. I wasn’t expecting a whole EP though.
