Digital backs used with wide angles are going to be problematic until much larger CCDs are available. The megapixel size is becoming less and less a quality factor as a larger CCD with less megapixels is more likely to produce a higher quality image.
However for fashion or still life where longer lenses are the more common optics used, a MF digi back is the most cost effective and probably most desired medium for capture. However unless you have sufficient work demands, and income from your photography to pay off a digi back in the first year ( and still make a real profit) the accelerated obsolescence of digital equipment will cost you dearly.
