Will any of the Mandelbricks ever leave the game?

I was wondering if the "Deluxe" skins from Mandelbricks will be Exclusive at some point in the future. You can buy any of those skins + each Mandelbrick in the Market right now and it doesnt seem like the Mandelbricks are going to leave at all. You can also still get both Mandelbricks in Operations and Warfare wirh the older one having a slightly smaller spawn rate. Does anybody know how this works and if they are going to leave at some point?
