It highly depends on what kind of books do you want to see. As far as I'm concerned, no, they absolutely didn't find a happy medium, because they didn't find a way so far to put out material that's not just FR and not APs.
I'd wait to see how VGtM will turn out and the "big mechanical expansion". Still, my biggest gripe is not the lack of pure crunch, it's the lack of support for other settings and their thematic crunch. I'd be happy, If they'd do something like the planeshift series, from time-to-time for supporting other settings and/or organizing better the setting content in their APs, like Paizo does. Oh, and using other parts of FR for their APs, nut just the Sword Coast, if they want to support that setting through just APs.
But I said these things many times before. If others are not interested in other settings and happy with the current products' content and berth, it's okay. But please understand that not everyone is.
I'm not against the slow release schedule, I'm not against the desire for avoiding bloat. I don't want them to stop doing their APs. I just wish they'd put out SOME content, even in small quantities, that I'm interested in. It's not about the quantity of content they're putting out, it's about the kind of content.
I'll reference you to my post above this one. They have finite resources to put out material. They can put out more material, but quality most assuredly would suffer. So it's a matter of prioritizing + business approach.
Here's how I imagine the discussion going at WoTC: "Ok, the core 3 books are obviously the most important. We need to devote our resources into making those three high quality material, because the entire game is built on that foundation. Once those are complete, we need to focus on our business model, and AL play is critical to that, so we'll work on putting out AL material and keep people in the FLGS playing those adventures. Yes, there are people who want every campaign setting we've ever done, and we have people who want a bunch of smaller adventures, and people who want a lot more monsters, and people who want more classes/subclasses/races, etc. Prioritization of these will be on which of these will be used by the most players. I.e., why would we spend our resources in creating a Spelljammer campaign book before we do Dark Sun or another monster book?"
"Ok, so we can only put out a few items each year, and we're doing it based on what the most amount of people will play. What about all those people who want more niche items?"
"Here's this thing we'll call the 'DM's Guild'...."
TL,DR version: They have limited resources in what they can create, and your interests may not be reflective of the majority's interests and thus are a lower priority for them to create and they logistically CAN'T create it without every other product suffering. For people like you with more niche interests, we have the DM's Guild just for you. I'll never understand the argument of some people who refuse to use any DM's Guild stuff because it's not "officially WoTC and therefore isn't good." What, do you think that the moment someone gets hired by WoTC they suddenly become great designers? Or that if someone isn't employed by WoTC they are horrible designers? That seems an awfully flawed argument to me. Especially since we have actual historical examples of people not employed by TSR/WotC who have put out some iconic material for D&D.
