Ok, I see a lot of people believing random things people are saying. So let me address this. Unless someone has a source, directly from Bungie. Do not believe what people say. A website with "information" on Destiny is not a source. DO NOT BELIEVE ANYTHING, unless Bungie says it. Way to many people on these forums are saying stuff that has no source from Bungie, and is not true, and everyone is believing them. The thread about the locations in Destiny is not a source. That is a fan website, nothing of that come from Bungie. And other things people are saying on these forums are not true either, as they have no source. The same goes for many other rumors you see on these forums. I repeat DO NOT BELIEVE THE RUMORS. Unless Bungie says it, assume it is false.
Their SOURCE is data mined information from the Destiny client they didn't just pull it out of thin air. Those People never said there couldn't be more content just that its unlikely that here will be much more. All of this information did come from Bungie in the form of files so....
