Some things to consider: first, don't panic about this content being on the disc. It's entirely possible these map markers are placeholders buried in the code, or markers from the testing phase of the December expansion which is likely being QA tested as we speak.... err... I mean type. I also wouldn't worry that there aren't any new planets shown on this map - this is a glitch, not a map update. That being the case, this information is likely incomplete and also subject to change. I am, however definitely concerned with the fact that these markers all appear on the same land masses we're already been running around in since the game launched. That would seem to imply the new content will take place, at least partially, in the maps we're all come to know extremely well by this point. If true, that's disappointing. I like Destiny quite a bit in spite of its flaws, but make no mistake, the lack of varied areas to explore is a MAJOR flaw, and I don't think Bungie can get any more mileage out of those maps at this point. Based on the mission names, it looks like the expansions will fill in some of the gaping holes in the story. This doesn't necessarily mean these missions were cut from the game to be added in later, it probably just means Bungie had a plan to flesh out some of the side stuff by way of expansions. Keep in mind, at this point this is all speculation. We won't know anything for sure until Bungie announces it, or until the expansions are actually released.
