I look foreward to MM maybe adding new planets in the future.
For atmospheres, I think they should follow something along the lines of elements that naturally occur paired. Like Hydrogen, Oxygen, Flourine, Bromine, Iodine, and Chlorine. Along with various byproducts of them.
As few new planet types, I would enjoy oceanic (suggested already), anti-matter, and maybe machine worlds/ancient lost worlds.
