I wonder how many commenting have done sports on an EVIL body?
Even shooting Kids on an EVIL is very hard when they are running around.
There is a long way to go before the optical mirror is surpassed
Maybe the Sony SLT system is the future, I remember pellicle cameras were the go to option for sports folks, and of course, no mirror flip means EF-s lenses could in theory be used on cameras with an FF sensor (and EF-s mount, obviously)
Olympus made a camera a few years back, the E-330, which was unremarkable in every way except that it managed to have both an optical finder and live view similtaniously, although like current DSLRs, it had to drop the mirror to get the best AF, maybe a combination of the two systems would be an ideal:
Full time live view, full time optical finder, with full time phase detection AF? Would make for a complex prism path and unusual camera shape, but then is it form over function, or function over form.
The only CSC that really appealed to me was the GF1, I really really liked the Panasonic Lumix L1 / leica digi whatever and would liked to have seen a scaled down micro 4/3rds version (again, optical finder and live view - adapted from e-330 but in a nicer shaped body) and with its aperture ring and shutter dial could be a fuji x competitor...
The problem with csc's is that anything other than a pancake just isn't really all that usefully compact.
