Mirrorless vs DSLR

[Kayaker72]

However, what I am saying is I can see some good reasons for manufacturers to be playing in the technology. They would do that to try to advance it for 1) cost reasons to reduce costs and increase profits, and 2) use it as a platform for future leap in technology from were we are today in order to drive up replacement sales.

I have a hard time seeing the current mechanical system getting that much better over time - some room for improvements, but leaps seems tougher. I would think there is more improvement headroom on the electronics side. However, this is just speculation... no real bases for it.

I completely agree with all of this. Of course, we've recently seen some small improvements like a new mechanical system to move the mirror rather than a spring loaded system, "silent" shutter mode, etc. But, I would also think there is more headroom for eventual change/improvements by improving the electronics and introducing them via a hybrid system as has been discussed or, potentially, eventual total replacement of the mechanical systems. My suspicion, and I think most on this forum would agree, this will be more of an evolution rather than a revolution.

I also wonder if the most headroom is in something unexpected. Completely new sensor tech like Lytro (who needs AF when you focus in post)? Or something that gets rid of the bayer filter like foveon sensors? How about a technology that can eliminate diffraction? Then, ultimately, the thing I hear people talk about the most and would even get me to replace my camera body faster than anything is dramatically improved high ISO performance.

I do not think I said was excited with what is out there now. Yes, I agree there is not that much to be excited about - especially when compared to the hype.

Sorry for any confusion, I cited your post as it introduced a topic that I wanted to look into and evaluate where I hadn't before. And, really, I did think it was interesting to consider the electronic vs mechanical shutter as part of all this whereas before had just thought about removing the mirror. But the "hype" or "passion" for mirrorless, especially in its currant state, was definitely from other sources.
