In this day and age, Directors hate to see their work revealed before the film hits the cinema. This basically drives them to fuel the media with misdirection campaigns giving false information and red herrings to throw people off the scent. I firmly believe this is what Scott has done all along.
The writers and Scott claim that the planet Prometheus takes place on is not LV-426, and also we will see no xenomorphs at all - Could be complete rubbish.
It's not unheard of - Michael Bay did it during the Transformers sequels.
This movie isn't a direct prequel, but has many tips of the hat to the original and takes place in the same universe.
