From the staff's perspective, there are a ton of things being worked on. Some things like the performance optimizations that Adam is working on right now will not add new content but improve upon the systems already in place. Things like these are needed prior to new content.
In addition, and it happens a lot, but a topic discussed previously gets tied into something new, which means that the new content will be completed before it is all released.
In particular these ^ topics are all still in the works and have not been forgotten about. Content isn't always something that can be produced in a week or month as the bandwidth for work is limited by the number of developers we have. I know in particular for the Booty Island Dungeon - Shane has been holding off on this to make it a special event.
Honestly it's just a matter of (mis)managing expectations.
I mean honestly man, booty island was opened how long ago now? There was all that buildup, advertising, excitement...and then nothing. And still nothing.
The content is always good once it gets done. It just shouldn't be announced until it's ready tor people to experience.
