between a business and a fandom. They have people who are paid to update the page every now and then; we have a 24-7 network of fans who are alert and online at any time and often notice within minutes when anything is posted online. And PJ is doing his own interaction via his Facebook page; not as a part of his contract/arrangement with the studio, so in this respect he's independent of them.
They may eventually have some exclusive news, but they probably won't do too much until the films get closer to release and become a higher priority to the studio PR department. If they run another official fanclub this time around, that will be where it's based.
