I want to know this as well. I wonder if they are planning sequels.
MAJOR SPOILERS:
Might there be a more complex interpretation of the ending (and with it a more complex interpretation of the entire story)? That not only does Louise see the future (and will in due course be sharing the gift with all humans) but that she might see not merely one linear future, but rather quantum and alternative futures as well as pasts? That these include an alternative universe in which the Heptapods leave without ever imparting the gift (and in which she and Ian also marry)? An alternative universe in which Hannah might actually be indestructible (if the Heptapods can be saved in 3000 years why couldn't Hannah also be saved by the deliverance of some cure unknown in a single plane of existence)?
One clue I have to this is the scene in which Louise learns of Hannah's diagnosis from the doctor. In that scene, Louise curiously doesn't at all appear as a prescient mother already aware of her daughter's fate (let alone one aware of it from before conceiving her child), but as any ordinary mother might appear learning of her daughter's terminal prognosis.

I came across this video today and found it very informative and enjoyable. An astrophysicist talks to the filmmakers as well as scientists about the plausibility of the science of the film. Obviously, there are limitations as to what can be verified, but I found it to be a fun video, and it's a lot less cynical than I expected.
