Chris,

I agree the silicon is going to be smaller, which causes the 1.x ratio on
the lenses.  I don't care about the physical size as much as the pixel
count.  I'd buy an Oly body that did 6000x4500.

Honestly, I'm ready to make the switch.  As soon as there is a body I think
is worth it, I'll sell off a big chunk of OM and add to my collection.  The
Nikon and Canon aren't there yet, for me.

Tom
