No. He's got it right. "4/3" is _NOT_ a "larger sensor".<g>.

Nikon and Canon aren't selling their high-end sensor technology to
competitors, and Olympus, with D-SLR market share in the low single
digits, is not going to develop it themselves.

Just like Sony.

Indeed. Those wars are fueled by those people who think (wrongly) that
better equipment makes them better photographers.

Likewise the better compact digital cameras.

What I think may have the most promise is Micro Four Thirds, even though
it's not an open standard.
