Here's the thing: as games grow and get more complex over time, they take longer to update. There are more characters to develop, the stories are more complex, and scripting and playtesting take longer. It's not necessarily that the devs are working less. Also, the overwhelming feedback I've received is that larger, less frequent releases are preferred to smaller shorter releases. It's more efficient because a great deal of time and work goes into just preparing for a release. Also, because each release generally requires redownloading and reinstalling the game, the release needs to have a meaningful amount of new content. Lastly, from a story perspective, I also think it's better to have fewer and bigger releases. If I published a new release every 4-8 weeks, the story would be delivered in small, disconnected chunks, which I think would cause it to lose its impact. That being said, I'm aware people are eagerly waiting for new content (and glad for it!), so I do try to work as fast and efficiently as I can given my constraints.
