While I prefer my Starbucks and tolerate Dunkin Donuts coffee, I find the coffee at WDW as fine. I don't think its the best, but I need my coffee in the morning and I find that WDW's coffee is good. I actually enjoy that first coffee so much I almost always have a second. In fact I buy the resort mug for that reason.
I can understand why so many of you have a differing opinion than mine on coffee. Coffee is an aquired taste that is not only influenced by the availabilty, regions and dining habits, but also perceptions. I recently read that the top selling take out coffee is McDonalds, not Starbucks or Dunkin Donuts (this is a fact stated in USA Today over the summer). IMHO McDonalds is the absolute worst coffee. I would have to be dying of thirst to drink that dreck! If I had to guess I would have been totally wrong. Then I found out why, simply stated McDonalds serves more people each day than the other two combined. It doesn't have to be great or good, it just has to be passable. So I doubt WDW will offer gourmet roasted coffee - unless they can make a bigger buck out of it.
