To start with, Good High quality, fast lenses are large (for APS sized sensors that is)

That's the question. Is that really so? Are these new lenses just normal lens designs for cameras with mirrorbox? Is it really not possible to make smaller high quality zoom lenses for mirrorless cameras?

Well YES when you want a fast lens you need large glass surfaces, so larger lenses.

Well, there's large, as in larger than a pancake, and there's large, like fast SLR lenses. If you don't have to clear a mirror box, even fast lenses can be reasonably sized. Look at the M-mount (or M42) lenses vs comparable SLR lenses. So Mike Kaminsky's question is a reasonable one.

Then to give a large FL the front lens has to be at a given distance from the sensor, nothing can be done about that ( or you have to make a miror lens or a colapseble one).

I think you mean the rear nodal point, but then that's what telephotos are for.

And take a good look at real high quality glas for every cameraq, high quality means bigger lenses...

Summilux, Summicron, Voigt 35/1.4, Nokton, even the Noctilux 50/1 isn't too huge for its speed. Compare to SLR lenses.
