its no suprise that the Star Wars Bundle is going to be 6-19 DEC. 6 DEC is the day before everyone can play the Battle of Jakku map (which is getting advertising of its own) and the 19th is the day after TFA comes out. You can bet that Sony will play commercials for the Star Wars bundle in theaters on the 17th and 18th as people will be getting to the theater early and will be saving their seats and sitting through the commericials.
Millions of people who are going to watch TFA are going to see an advert for a cool looking SW game, with a "special" bundle price that ends in 1 day! If they love the movie (almost everyone will on 1st viewing, it will be after time people accept it was not good as they hoped) they may impulse buy that awsome looking Star Wars game with the PS4.
I'm curious about as to what stock will be available for the SW bundle. Naturally, SCE would want to have as many as they can stockpile before the release, but there is a finite number produced which means depending upon availability, they could sell out of those bundles.
On a related note, I did see a half stack of PS4 bundles on Black Friday that morning, which means they didn't sell out at the midnight opening at least at that one location. I wouldn't have been surprised if those were gone by closing though.
So the how many can SCE sell may simply boil down to how many bundles are available.
