What i was trying to convey was that they won't add anything new. I remember a thread on here where many people had some great ideas on what to add to the DM's Guide. My fear is they won't add anything new, but instead, be so hyper-focused on the layout and order, that they don't add new ideas.
For example, someone on this board spoke about adding a way to implement optional equipment and inventory rules. Pretty cool idea. Or they could add specific rulesets for types of campaign settings. But, I think once they finally get the structure the way they want it, there will be hesitancy to add these (or any) new ideas.
Hope that clarifies. Sorry about being so vague.
