Micro 4/3 sensors are extremely tiny and much, much smaller than APS-C sensors. f0.95 on a 35mm sensor gives you insanely shallow DOF and even on APS-C you're getting good isolation but on a m4/3 sensor the you don't get as much of the shallow effect. The OM-D + 75mm f1.8 lens for example produces some nice DOF but compared to say a 135 f2 on a D800 or 5D2/3 the bokeh will be harsher and more busy with more DOF.
M9's just eat up those kinds of lenses though you need a 4 or 8-stop ND just to shoot it wide open during the day

Not exactly. Micro 4/3 refers to the body depth, not to the sensor size. The M4/3 sensor is the same size as the DSLR 4/3 - 17.3 mm x 13 mm for a crop factor of 2, instead of the APS-C 1.5-1.6. And bokeh isn't a factor of the sensor; it's strictly the lens design. Saying the OM 75 1.8 doesn't have the same bokeh as a 135 f/2 on a D800 or 5D2 (and whose 135 f/2? They aren't all the same.) just ignores that distinction. Put the 135 f/2 on a 4/3 body (assuming an available adapter) will show the same bokeh (not DoF, unless you crop the larger image to match, but bokeh) as it would on an APS-C or a 24x36 mm "FF".
Fuji is just so expensive... If i was going 4/3 I'd go EOS-M right now... strictly because of the ability to use EF lenses with little issue.
Though I'm holding out for full reviews before making my decision.
EOS-M isn't 4/3; it's the standard Canon APS-C 1.6 Crop Factor. Same as the Digital Rebels, 10-60D and 7D.
