Also remember that the above discusses print products on one hand and pdf distribution on the other.At the end of the day... I don't think you're ever going to get what you want because I suspect they just make more money bundling 7 "adventures" together into a single book (calling them "Chapters") and having DMs buy all of them at once... then they would by spending the same time, resources, and money on 7 completely different modules and selling them individually (where any DM might only pick up 1 to 3 of them.) Which means your only choice is to buy the full-sized books and treat those "Chapters" as individual stories with the serial numbers filed off, and then mixing and matching different chapters from all the books together depending on where the PCs want to go. So you might re-route off and away from the Caravan chapter in Hoard, and instead find yourselves advancing on Wave Echo Caves instead.
I think the simplest answer can be summarized as:
1) the hidden truth in rpg publishing is that core rulebooks earn money. Adventures never earn money.
2) the game needs adventures anyway - releasing a game without official adventures is doomed to failure
3a) lets limit ourselves to the surest bet: huge but few megamodules that everybody buys so we don't lose too much and still fulfil the necessary supply according to 2)
and
3b) lets leave the "smaller adventures" bit to the fans and 3PP. Even if that means no print products (since if we won't do it, small-time operations sure won't either). But there is PDF.
So lets open up an "app store" where people can publish their adventures as low-cost PDFs. We (WotC) wouldn't want to do PDF products anyway, because I) we're in the paper publishing industry and II) PDF products are seldom seen as "big releases" (not official enough, not enough quality, not "tangible" enough)
But we can still recoup our costs by skimming 20% (?) on top of what people would do anyway in return for a "safe haven" where they can use our IP safely.
A win-win-win scenario for us, the publisher.
Still no 32 page modules in our LFGSs for us, the fans, though.
And a bewildering array of DMsG offerings of hugely variable quality with next to no critical analysis to help you decide what truly is good.
