Tatooine is just about the last place I want to revisit, for all the points already mentioned.
"...this is the planet it's farthest from". Unless Lucas gets writer's block.
However, at this stage we don't know what they have planned. With any luck, if we have to see it -yet again- hopefully it will be a ten minute revisit early on to go get Luke out of some sort of self-imposed exile and then we leave it behind forever.
