No, we do not yet have the micro 4/3rds to end all micro 4/3rds cameras. Here, I stay away from things like, "Where's the pro micro 4/3rds with the weatherproof body?" and such and concentrate on what we know are the shortcomings of current bodies.
G1: Not compact enough, not as attractive (sometimes it means something) as the E-P's and GF1.
GH1: Too expensive with the obligatory 14-140mm lens.
GF1: Poor resolution EVF option.
E-P1: Slow and hunty AF and no EVF.
E-P2: AF no better than E-P1.
Now we need:
The AF of the G1/GH1, the compactness of the GF1, the EVF of the G1/GH1/EP-2 (built into the body).
Will the GF2 combine it all?
