No love for the EM-5 in here?
I know, I know..it's probably just a reflection of the smaller user base here.

Anyways, I think Olympus nailed this one and I would love to use this as my lite take everywhere camera.

Sensor size: IMO it's the Goldilocks of sensor size. Not too big, and not too small. A good trade off between size and performance.

Lens selection: probably the most mature in the mirrorless or CSC segment. The fast zooms are coming this year for those that want it. Not sure what else is missing, maybe some native fast tele primes? Not that I need them and kind of defeats the purpose of a compact system so they might never come.

Bells and whistles:
EVF
ibis
Weather seal
Dual control wheels
Faster AF
All very photocentric features

I use to own a GH2 but sold it for various reasons so this might be try 2 with m43 for me.

If only there were some native wireless connectivity. Oh well, I'll have to experiment with Eye-fi then.

Just waiting for some production camera reviews.
