I can't imagine it will ever happen in a standard stateroom. The cost of the pods, disposing of the waste, Keeping the machines clean. I think the cabin stewards have enough to do. I for one don't want to go back to my cabin to get a free cup of coffee. I know nothing is free, we pay for it one way or another. And the pods do not make great coffee, ok, fast but not great. I enjoy my coffee in the Atrium.
