Very interesting camera. If they can really put those features into it,I would be very likely to get one. I don't see a mic in port (nor a headphone jack ) and for that price I would expect one. (people are complaining about the lack of a headphone jack in the EOS M, which seems sort of lame to gripe about given that Canon is just about giving them away the M right now.
Is it on the side of the camera not being shown? And does it have the headphone jack as well as mic in?
The stabilization you show is quite remarkable.
If the camera can really produce video that is on par with the GX3 that would be quite a travel camera. My EOS M footage and stills have been very good, but no better than a 7D, which is what it really is. For travel I have been ok with the results, especially stills, but would love to have better video quality, which is what I end up getting paid for.
