Except Apple has proven time and time again that they're too cheap to hire more engineers to actually keep dedicated resources on projects, and instead shuffle teams around and let products wither on the vine (currently see: iWork, iLife, Aperture, etc.)
Apple determined that constant updates and growth on those products doesn't contribute enough to its profits to dedicate to it on a full time basis. They also determined that there is little immediate harm done by ignoring them at the moment. But, like with meaningless product fads (content aggregation), the real problem is in the long term. But it seems Apple manages to put out enough new versions to stop the slide from being terminal. Only those of us who already own the product, or have been watching attentively to the state of the product, notice or care about the lack of big updates. Most everyone else either uses the products as they are and is content with them, or uses something else.
Content *creation* isn't the focus these days. The market for the tools is saturated. The tools themselves have gotten robust enough to level the playing field enough that anyone can be a creator. Adobe is bloating their product with garbage just to keep repeat selling. They've had to start pushing a subscription model because there's nothing compelling to offer for upgrade lures. Everyone is trying to make money on other people's content, because that's easier and quicker and leaves no groups of angry abandoned users once the product goes belly up and the opportunistic executives move on to the next money making fad or retire.
Eventually the content creation tools will start to mature in efficiency, under the surface. That's all that's left, aside from the occasional dramatic new technique to select or manipulate more specific parts of data in an image or audio.
I wonder what a fully Apple-native 3D modeling and rendering package would look like. All the existing tools are horrifically inhumane. That's a branch of software development for content creation tools that is still shamefully archaic and primitive. But again, the market is saturated and there's no clear reason to develop anything new. Certainly not from scratch. The expertise is really lacking in the job market, too.
Apple is only looking bad to a select group of people paying close attention. Like myself not buying the current version of iWork because I don't know if I'll get screwed on purchase price when they do release a big new upgrade. I have extremely limited funds, though, so I'm sure that most people aren't sitting on their hands waiting like myself. I'm not hurting Apple waiting and so Apple isn't really hurting itself. We aren't the example of Apple's preferred target audience at the moment and that's ok for them.
