JoJu, by advising me to ignore you, you just want your claims unchallenged
I'm sick of the "DSLRs are dying" mantra; they were supposed to be long dead - and guess what... 3:1 in their favor.
Despite all those "collapsed firewalls" you're talking about, the MILCs can only gain ground slowly, very slowly. I just can't believe your "X will happen, and after that..." because I've seen such a promise over and over again. I'm not particularly gullible.
Things changed since 2013 - namely, MILCs aren't growing anymore. What you're doing is called confirmation bias - and mathematically incorrect, as you're assuming a constant growth for MILCs - when, as I said, they aren't growing anymore.
The MILCs are a long way even to just reach DSLR levels; but to completely replace them? That would take a while.
And talking about some distant future is a mistake, in this case. Sure, Ricoh Imaging should plan for that eventuality (and I believe they'll enter the large sensor MILC market, at some point). But, as of now (mid-term planning), the DSLR market is much more lucrative for them.
Think about it: breaking into 10% on the DSLR market is roughly equivalent - as volume - to fighting for leadership in the MILC market. Planning for the future is all nice and good, but they can't starve themselves until that future happens; they need money, they need to sell. They need a product line which would work now (and in the immediate future), which would bring money for further development/R&D.
That product line is the K-mount.
