Im sure this has been a forum post before, but i just wanted to make sure they realized all the hints that i have seen as of late and others that people have discovered that i didnt know about. A small amount of spoilers also

1. DLC dealing with BoS. First off theres the abandon BoS bunker that i still have no idea what it is used for. On top of that there are various quotes coming from the BoS quest line. Not actually dialog but the dialog that is stated when you walk past someone or try to talk to some1 that you cant open a dialog with (guards, etc)

2. DLC dealing with Denver and the legion. Someone in the fort said that they get most of their dogs from Denver. I suspect tat this could be a possible dlc, but not as likely as the other.

3. Powder Gangers DLC. This one is by far the most obvious. A bit of spoilers fyi. Through a little bit of talking to powder gangers and people involved with them i have discovered that the main leader of the powder gangers has actually left and "gone up north". It also states he has some big plan to get back at the NCR. If you travel north you will discovered a location by the name of The Norther Passage. The entrance to the cave however is blocked off by rocks. The rocks show signs of an explosion could have caused them to fall and all things considered most likely involves the Powder Gangers leader.

4. Enclave DLC. Simply because Enclave are just so cool . Im sure that the BoS dlc will include the enclave in one way or another.

Actually we have an http://www.gamesas.com/index.php?/topic/1138694-dlc-suggestions-3/page__hl__dlc for FONV, you're welcome to repost this in there.
