Best m4/3 body for manual focus lenses?

I've been going back and forth about whether to pick up a mirrorless/system or simply to get a G1X when they start shipping. One key decision point for me is the ability to use my manual focus Nikon glass on a mirrorless body - particularly my Voigtlander 40/2 for portraits. I know that Sony and one of the Samsungs have focus-peaking, which makes MF real easy, but what of the m4/3 bodies? All I've seen is the center highlight area that my old LX5 had (similar to earlier m4/3 Pannys, I think), which I didn't use much but I can't say it seemed all that useful. At this point, what is the best m4/3 body on which to use manual focus?

Thanks
