the closer i read it, the less good the glass seems... 2.8-5.6 is pretty shitty and if the focus throw is not huge i am going to be seriously let down, not to mention, at that size, there is no way it is internal zoom and focus, meaning follow focus and whatnot is nearly impossible.
My take after reading the article and looking at the specs, Is that Canon basically took the Panasonic Lumix GH3 (3 not 4) and gave it a fixed lens. 1080@60 and 4k@30 is really not that great at all considering the GH4 is $1k less and you can put great glass infront of it with similar results.
It seems like buying a used GH3 with a metabones adapter for canon, or even a GH4, would be a better option.
Playing the devil's advocate here a bit...
except the gh3 doesn't do 4k lol, also follow focus isn't impossible as long as you leave it for a set focal length/there's ways to rig it up.
the bitrate's also higher than the gh4 could do in UHD and idk man, try finding a zoom that has a constant aperture for a 10x zoom range for under 50 grand and then come back and complain about the 2.8 to 5.6 of this one.
that being said, 8 bit is a bit disappointing and I think the trend should be going towards 10 bit... but in all honesty, this camera isn't all that impressive to me either although i don't believe it's as bad as you make it out to be
