No need. The 35mm format if the manufacturers want to capture a bigger market and more pros will need to migrate to larger sensors just as Leica have seen the light.
The 35mm format is a lousy format to begin with and was born as a compromise, now they have the opportunity to break the shackles from that restrictive format.
Since this forum is visit by makers and dealers you'd think the positive reason for these type of posts is for the camera makers to learn and respond.
You'd think the specialty camera companies' response to the high end dslrs would be higher iso, better lcds, live view, more lens options, faster delivery, better price. less complication.
When I heard that Leica was coming out with an almost medium format camera from a clean sheet I thought cool, other than price maybe they'll get it right and once again these forums are a good starting point.
Well, I guess the the "I like to shoot slow thread", or the "complicated software thread", or the "low iso works better with pro 7 section", or worse, "I can wait as long as needed for lenses thread" is where they set the bar.
Seriously, you'd think Leica read the responses to the Mamiya ZD and translated it wrong or thought after the Hy6 there really was a place for a $50,000 camera system that was slow to bring to market.
I still don't understand this format thing or why people get so hung up on it, because almost medium format has what 5 formats? The Dslrs have at least 4 formats and the funny thing is on any professional set the only format that any client sees ( or cares about) is the size of the monitor.
