I have tried it on 'Kina' on Tuesday too and actually enjoyed the EVF pretty much. Off course, nothing beats an OVF as in the current and former H lines, but I found the accuracy and speed of AF quite ok. I have used on the past couple of years Fuji's X-100 EVF-OVF and believe the one from X1D is much better than the one from X-100. Although i cannot compare it to the Leica.
In live view with the touch LCD it is quite nice to quickly double tap on the spot where one wish to have the focus and the activating the AF. Changing the AF point with current production models is not yet effective but was promised to be updated by new firmware release.
Auto ISO is there but did not really work very well. It seemed to me some missing user entering possibility (similar to Nikon's approach to limit e.g. slowest shutter speed whereafter the ISO is increased automatically).
The new 30 mm lens is nice and quite small, but I guess the HC 28 with the adapter (which was on display) will do the job also quite nice. It was confirmed full exposure metering and AF functions with newer HC/HCD lenses. No tripod mount on the adapter yet, next version will come with (I am just thinking now that I will eventually try to mount myself an Arca plate on this adapter by just screwing and threading a 1/4 inch hole...)
Back button AF with manual focus setting on the shutter release works well, which is important to my habits of shooting.
AND it comes also with the yellow-golden shutter release button....

I am definitely holding on to my early order and waiting for delivery within the next 2 weeks as it was promised.
