Forests and Trees

It bothers me that WOTC doesn't seem to understand that D&D is a game and not a marketing contest. The closest they seem to come to providing content is when they have a new product to hawk. "Let's talk about the white dragon... oh, you can buy these miniatures of it soon!"
They have created a workable game system, and I like it. I don't think I'm alone in that. So why can't they generate some actual content for it?
Where is the reincarnated Dragon or Dungeon? Weren't they put in suspended animation last year about this time until the new system was out and they could reemerge in some form?
The Eberron content they added recently did offer a useful insight into magic item creation, particularly scrolls and potions. It may be the only useful item in the document, but it offers a way to handle those concerns. The DMG suggests magic item creation of the most common magic items takes 100 GP worth of time and money, with a spell caster able to contribute 25 GP of effort per 8 hour day. So a Scroll of Magic Missile takes 32 hours over four days and costs 100 GP to create? Yet once that is accomplished, another spell caster can spend 2 hours and 50 GP to scribble it into their spell book, with the time a result of figuring out the original caster's shorthand. This is a flawed system.
In Eberron, apparently, a certain class of wizard is able to expend a spell slot and spend 10 minutes creating a potion at 2nd level, and the same at 3rd level to produce a scroll. This is offered as a "path" available to spell casters.
Frankly, this is something that should be available to all spell casters automatically (at least, the primary casters - clerics, wizards, sorcerers, and druids - warlock powers are derived from their pact, and paladins, rangers, and eldritch knights are primarily fighters).
