The beauty of medium format is that wonderful larger size of negative or in this case, sensor. People are not going to abandon a 48mm sensor for a smaller one.
This, I think, is the key point. With sensor size, bigger is better; otherwise, there would be very little reason to buy a 5D over a 40D. A medium-format digital back has a similar advantage over a 5D that the 5D has over the 40D. The H3D is going to have much much better noise performance at any ISO, will show sharper details, etc...
35mm DSLRs were this expensive not too long ago...I suspect medium-format digital will grow in popularity as the price comes down.
MFdigital backs have very limited iso ranges. the iso range of my aptus 22 back by way of example, is 25-400. and depending on the back manufacturer, even using the same chip, the iso performance of various backs may yield different results as it relates to noise...with a few exceptions the iso range of most of the digital backs falls somewhere between 50-800. i can push my 1ds3 and 5d's to iso 3200 if necessary. the d3 and the 1d3 can easily do iso 6400- you just can't get there with a mfdb. if you add the fact that i can shoot sub f2 with numerous dslr prime lenses or at 2.8 with a couple of zooms(and the fastest fixed mf af-zoom(mamiya) available is f4.5 and af prime is 2.8) you begin to better appreciate some of the other strenghts and weaknesses that characterize the various formats.
one of the advantages that the dslr companies enjoy(well at least canon and sony and to an extent nikon) is the fact that they develop their own sensors...the growth in mf sensor development is hamstrung as the back makers are relying on third parties for sensor technology. this will continue to add a level of cost that the larger dslr companies do not have to contend with.
