Indeed. But do remember that digital sensors have substantially higher resolution than film, and if your lenses can cope, a (relatively) small sensor is more than adequate. Years ago I had a Bronica SQ 6x6, and I have to say that the 37mm square sensor in my Megavision goes waaaaaay past anything the SQ ever managed. I've never used 4x5 film, so I can't compare my Better Light's results in the same way, but I *can* say that the Megavision is damned close in terms of image quality (and *far* easier to use). Mind you, last I talked to the Megavision people, they were close to releasing a new 39 megapixel version, which potentially might even be available also in monochrome, though I do suspect that, at that resolution in mono, the lenses would actually end up the limiting factor. Unless you have a mini-view camera and one of the new breed of ultra high resolution 'digitar' lenses.

I don't think I'm going to jump in that direction any time soon, though -- I rather like the equipment I have now.
