They won't. They'll remain completely silent about all of it... just as they did when those data-mined details came out explaining every last thing you'd be able to do in the game during the beta. All of the naysayers... "It's just a BETA! Why would they have all of that info on their BETA servers!? Bungie is smarter than that!" Funny how nobody talks about that anymore... you know, how many people were mad that the only place to explore on Earth is the stupid Cosmodrome... and how all of the people were like "It's just a BETA! there will be more on release!" Mmhmm. Sure.
