I think that the adapted lens potential can work a bit differently with the miniMF systems like the Fujifilm than it does with FF and smaller. While I agree that not all users will be served well by those non-native lenses, especially if they surrender automation and communication with the camera electronics, I think that given the kinds of things people are more likley to do with such a camera, that the use of adapted and largely manually operated lenses for things like landscape photography myay not be quite such a stretch.
The Sony example actually tends to support this a bit. While not everyone is happy with adapted lenses there in situations where fast automatic lens operation is critical, among folks like landscape photographers, who most often focus manually, the Sony bodies have been perhaps more popular than in some other kinds of photography.
In addition, while quite a few of us here may regard miniMF format as something to move up to, among current MF (and to some extent LF) photographers, they look at it as something that then can move down to while getting very high quality in a much smaller and lighter package. Quite a few of them already have MF lenses that they would happily use, at least at first, on such a camera.
I have no illusions that this will appeal to all photographers who are attracted to the camera, but I think there could be a significant number. (I have at least one nice MF lens that I\'d love to use, a lens that isn\'t yet covered by anything on the Fujifilm road map.)

My general feeling is the one gets miniMF because he/she wants better image quality of one sort or another. For this reason, I don\'t quite get the idea of considering the use of FF lenses that may compromise resolution and/or light transmission near the corners of the 33 x 44 frame.
When I had my 1D mkIV with its 1.3 crop APS-H sensor I found quite a few APS-C lenses would cover the APS-H sensor (sometimes you had to crop a tiny bit to remove black corners).
However the quality of the areas outside the intended image circle were generally very poor - so I completely agree with you there - it wouldn\'t be any good for landscape photography for example (unless you had no other option).
However the Sigma 30mm f/1.4 I had would work well wide open without black corners, and gave me a 43mm f/1.8 equivalent (something no-one was offering for full frame). And since the corners were generally out of focus at f/1.4 softness wasn\'t an issue.
That\'s where I see the uses for mounting full frame lenses on the 44x33 Fuji camera. It would open up a range of looks which are currently not possible on any other system - 40mm f/0.79, 67mm f/0.95, 107 f/1.1 (35mm equivalent).
And before people complain about eyelashes in focus, superfast lenses are not just about extremely shallow depth of field, they also extend the focus distance at which you can still get separation of subject and background.
There\'s also a 16:9 crop mode, which would use a 44mm x 24.5mm region of the sensor - making it a widescreen 135. This also reduces the required image circle by 5mm!
I can\'t say that I disagree with what you are pointing out as far as what is physically/optical possible. My point, I think, is not to deny that but to think about the fact that the appeal of such things is likely to be limited enough in this market that we are unlikely to see adapters for the lenses from a smaller system. On the other hand, given the number and variety of existing MF lenses floating around that could work well and provide good corners and all the rest, I think that is where the adapted lens offerings are going to happen.
Take care,

I do think that adapting existing MF glass will be the option that makes the most sense. I for one would like to try system V series glass on it particularly my 120mm makro-planar. I have heard they have done some custom work on the microlense\'s to make it more tolerant to older adapted glass. They have also added a lot, I believe 12 electrical contacts so it will be interesting to see if they are planning to natively support electrical compatibility with newer lenses. There\'s a lot of great older MF glass floating around at fairly bargain prices too
