There is a grand tradition of deception and misdirection in the production of a Star Wars film. Dave Prowse was given phony dialog to say on ESB, and there were fake script pages on Return of the Jedi.

It's not a stretch to imagine J.J. doing this one better, and shoot fake scenes.

I have no doubt that Abrams is playing with us. It's worth noting many of the rumors starting rolling out after photos\concept art were leaked, interviews were given and official news released. It's as if people are trying to connect the dots with what known information is out there. The rumors even got the names of some of the characters wrong... unless if the officially released names are aliases, which is another rumor.
