The most impressive part of the announcement to me was how they were able to keep all the details of the system to themselves until the launch. Normally Fujifilm leaks a ton of stuff before launch, probably on purpose, so both existing and potential customers are able to foresee a bit into the future. Just do a bit of research and you'd be able to see X-T2 was coming in with a 24MP sensor and weird battery grip, eg.
About the camera(and the system of course), I'm really surprised that it doesn't have a leaf shutter, at least in some of the lenses. Fuji definitely knows how to build leaf shutter lenses (most probably more so than any other company) but I really can't understand how they left it out on this one. I'd expect at least one on the roadmap.
Otherwise I like the camera. I don't think it's much more expensive than other serious offerings and it even looks good. Looks like it might even have a bit of space inside it for a slightly larger sensor, so I wouldn't be surprised to see a 54x40mm sensor in there somewhere one day.
I'd be much happier to see the Hasselblad's concept announcement to see the daylight though.
Or you know, just a 6x6 digital back for my 500C/M would do. Not that I'm not happy shooting film, but I'd simply ditch every other digital camera I have if I had such a back and buy a X100T for lightweight and use the HB for pretty much everything else.
