So which is better? "GH3" or OM-D?

GH3 ticks almost all the boxes:

• True pinpoint focus spot capable of cutting through overlying branches, as was recently shown on this forum.
• Or very small focus box as in GH2 with PIP 4X central enlargement on un-enlarged background in MF assist. mode, and should be hand/monopod holdable with 300mm.
• Electronic shutter.
• Superb video for those who use this also in nature work as I do.
• Your birding/nature stills settings of choice can be set up in one of the three Custom modes on main dial, and video on another for rapid transfer.

And focus peaking in a future update as hinted at by Panny firmware engineers last month?
