Yes I suppose as the land is set in the Avatar future timeline we are in the future, however I don't think their is anything in the land that would clearly signpost this? Unless sci-fi = the future? We haven't even seen Earth in the film to know if it is our Earth or an alternative timeline?
I think their is a big differences between a vague future on another planet/moon versus a specific time period about 100 years on earth. Just look how the whole of Dinosaur sets up sending you back in time to see dinosaurs, they don't just happen to exist because when you walk into Dinoland you go back billions of years in time.
