This is interesting: http://www.mirrorlessrumors.com/son...rame-entry-level-aps-c-market-is-slowing-down Let's suppose that FF does eat up a large piece of the APS-C market. That means the smaller system market will be between 1 inch and mu43. Both have the advantage of smaller lenses and we can see the 1 inch sensor moving through the compact market. As sensor tech advances, both could easily be good enough for most of current enthusiast photography. Mu43 is arguably there now. It's not impossible to imagine a market dominated by FF and 1 inch? What think ye? Obviously, this is just a bar conversation so no life and death issues here.
