Ok...looking at the video, that difference looks to really be no big thing. The internal chassis and lens mount support are the same, just the front panel is different, so it may feel more rigid in the hand when shooting with really heavy lenses supported by the camera alone. Since I don't plan on putting anything much heavier than a 135/2.8 on this thing, I'm fine.
Though, to be honest, looking at the 'lens roadmap', I'm somewhat concerned about lenses for this thing. Based on the 35/2.8 and 55/1.8 pricing, the good lenses are likely to be crazy expensive, and if the leaked image of the potential Zeiss 85/1.8 is true, that thing is also ridiculously big for an 85/1.8. I think I'd be OK using this as an adapted lens machine with the great focus peaking and big clear EVF, with only probably the Zeiss 24-70/4 as a native lens (eventually), but I also don't want to buy in, use it for three months and realize it was dumb to get and sell it.
