The only things that can really bring down the costs are mass production (not going to happen with premium equipment), new manufacturing techniques, cheaper materials (which is certainly not the current trend especially when you look at aluminum), and cheaper components (less expensive drive systems, encoders and other off-the-shelf components).
I feel that things that bring down the costs are already starting to happen; yes they may not be premium but that's how innovation happens, cheap and simple. My point being today's premium will NOT remain premium if things progressed the way they seem to be progressing with today’s so called 'non-premium' mounts. Non-premium production is what's driving the revolution, not the premium. Premium just can’t afford to try innovation in quick repetitive cycles the way non-premium can. And yes, premium eventually will benefit from non-premium experimentation and research.
Non-premium production is which lends itself to trying new things in quick production cycles and same goes for the buyers of non-premium products who make those products expendable.
To use a recent example of one of one of your customers who started off with $5K budget but ended up with or will end up with around $30K by the time all is said and done with premium purchase. Now that purchase is not expendable. Hypothetically speaking, had he spent what he originally planned he wouldn't think twice making his next purchase in few years for the next big thing. Such expendability is what drives a revolution and innovation in my opinion on both ends, manufacturing and consumption. Regards
