Mirrorless really doesn't change the end result of digital photography at this point in time. It doesn't really even change that much, the way in which the user operates the device. It merely allows the lenses to be mounted closer to the sensor which has some technical differences and in order to leverage it for smaller equipment requires all new, smaller, re-designed lenses, yet, there already are product lines for this, that's Panasonic and others.
At the end of the day, especially if you are a competent editor, digital photography is sort of settled. We'll continue to get faster speeds, better ISO/less noise to a point, etc. There's also medium and large format considerations, which have great IQ and usually have slower lenses due to the nature of physics. And other than High ISO at low noise which is starting to show up rapidly, and the ability to print HUGE while in high detail which medium and large format already covers, -this game is figured out. The people left who can't create amazing images just aren't good artists, don't grasp digital editing (which is the equivalent of the darkroom developing process and is highly important) and they just need more practice.
The innovations to come, will mostly be in lower prices and converging technologies (like video and photo being done affordable in one unit, which we are already in the middle of). The rest of this non-sense is about money, and we all see how well that is going for the world.
Humans continue to do things in outdated weird ways. I mean, we go down to the camera shop to look at what's on the shelf and if something sucks and no one buys it, it eventually ends up in some garbage pile next to a rain forest along side all of our recently obsoleted garbage (and doesn't make for the nicest nature photography...) Would make more sense to be making the equipment on demand with on-sight recycling for botched and obsolete designs. Would be fun if the Camera manufacturing plants were eventually turned into a "public works resource" where people of all ages and skill levels could go to learn and create their own cameras and whatnot (same for all other fields, music equipment, computers, etc.). The market/money and marketing are creating a lot of needless waste and they are slowing down the progression of technology.
Of interesting note to the above, a digital camera sensor is basically the same thing as a solar cell (which we obviously all need to start getting involved in), an array of PIN photodiodes. When light hits these diodes that make up the sensor, electrons are collected. Now in digital photography, these values are counted/organized and stored on disk and then read back later on a monitor etc., as your pixel values that you would see in photoshop. In solar energy mediums, these same electrons would be stored for their energy in something like a battery, or converted into some other form of energy, like water heat. The point being, if the people take over the development of Photography and Solar, we'll all be a bit smarter, we won't kill ourselves and the planet, and we will all have the nicest cameras... Now how's that for some innovative vision and IQ, or do you still just want a mirrorless camera body?
Here's a link to learning electrical engineering at home, from the beginning, it's like a 40+ hour, free, educational series some school posted on youtube, and it's awesome. http://www.youtube.com/watch?v=ZZEZUysFPDY&feature=relmfu
