[quote][b]Posted by:[/b] OrderedComa The Knights aren't really Forerunners, not exactly...we don't know what specifically they are yet, so I personally wouldn't be calling them Forerunners until we actually get some canon info on them from the game itself.[/quote] I thought it was fairly obvious and well-known what they are. The Knights, Watchers and Crawlers are Forerunner Promethean-Class Combat Artificial Intelligence Constructs. Called "Promethean Knight" etc because they are controlled by a Promethean Warrior; namely - so far as we can tell - the Didact. Unless there is some scrap of information that someone can point me (us) to showing that they are more than simple AI Constructs, and more specifically the bit about them having an "Organic Core." The smaller arms aren't actually organic, and if I'm not mistaken then share the same "Joints are magnetic fields holding the pieces together" mechanism. As for their difficulty, I don't think it will be dumbed down at all. In the last "Behind the Scenes" video on the Prometheans, it was mentioned that the Promethean Knight (the lowest of the Knight tiers,) will be one step more difficult than the highest rank of Elite (Zealot.) So on Heroic (the "canon" difficulty) and Legendary - perhaps even Normal - I have a considerable feeling that the Promethean Knights and succeeding classes will be incredibly formidable.
