I'm pretty sure that m43 cameras CAN be smaller than APS-C ones (the fact that they aren't so far is either because of ergonomics, or because Sony is better at miniaturization of camera bodies than Panasonic/Olympus).
But they key thing is, how large /heavy the lenses are. And there are not enough data points to be sure right now (simply because NEX doesn't have enough lenses), but it seems lenses of comparable quality are smaller / lighter in the case of m43.
Which seems logical, given they have to cover slightly less area.
Originally posted by dankoBanana the EP-2 is nice, but I don't see someone using it @ ISO 3200 without hesitation (or 6400 for that matter)
Again, that seems more of a property of EP-2, rather than m43 as such. It is simply using an old sensor (from 2008). The G3 will come out with a new generation of the sensor, and we'll see what it can do. Olympus has probably also procured a different sensor for EP-3.
