This is ridiculous. The expansion content is in production right now and all of it is likely in varying states of completion. What is clear is Bungie has a very clear production plan and corresponding schedule for future content. Which is not only the responsible thing to do, but is likely necessary for their production. If they didn't do extensive planning and pre-production, it's likely things would take far longer to get done. It's worth noting that many larger game studios and large game productions work this way. There is no evidence that the content is done or "on the disc". If it was it would of been included in the final game, or up for sale as DLC right now. Theories about Bungie and Activision withholding finished content is dripping with paranoia. Either way, almost none of us are familiar or experts in game production, or are familiar with Bungie's iteration driven design philosophy, so it's patently ridiculous for anyone to claim Bungie is just sitting on all kinds of new strikes, raids, missions and maps they're happy with and feel ready to ship. Obviously we have every reason to believe the opposite.
