This is true, but it is due more to price on those particular products, (P30, Aptus 65, and now H3DII-31). What was exposed from the last few batches of digital backs is that the slightly higher premium for larger sensors (49 x 37, 22MP, Upper teen $ - low $20K) vs higher resolution (44 x 33, 28/31 MP, low $20K - mid $20K) was not acted upon. Instead, users chose the lower cost, but higher resolution (and more sensitive) sensor.
But also, until Hasselblad dropped the price on their H3DII-31, most of my H3DII sales were H3DII-39. This is because the price delta between H3DII-31 and H3DII-39 was not dramatic enough ($26,995 vs $33,995). This also explains to some degree why Hasselblad made such a significant price adjustment. Now I will expect - and have already seen - H3DII-31's selling in greater numbers than H3DII-39's.
It is human nature to want the latest and greatest. And despite all the "Oh, 22MP is more than enough" protestations when rumors of 30+ megapixel sensors were rampant, the vast majority of purchasers have shunned 22MP, even though it is relatively low in cost.
That said, 60+ megapixels and higher are on the way - at some point. I do feel that without some form of variable resolution selection at the capture stage, digital backs at this megapixel count may be the first crop of high resolution products that do not produce a volume sales advantage over their lower resolution counterparts.

On this I somewhat disagree with you Steve, at least in regards to the Hasselblad and the P30+.
I went with the P30+ not for the reduced cost or reduced sensor size, but because it had better high iso qualities and because it looked fractionally smoother than the 22mp chips. There was also the added benifit of less moire.
I don't want, need, let me put this again, want higher mpx than 20 to 30, but the only thing that would get me to change from the p30+ if there was a 1.1 (excuse me 1.16) crop instead of the 1.3 (excuse me 1.26) crop.
More real estate would be worthwhile, if only to make my lenses a little less squeezed.
In fact I think cropping that 31mpx sensor was a mistake and medium format had a big chance to offer a big one up on 35mm with a microlensed sensor in 1.1 size, especially if they held to a good price.
I don't think you can underestimate how important higher iso is for a lot of work photographers who specialize in people. Higher iso on a medium format back, already working with a slight bellows factor and slower lenses makes a huge difference and unlike most of the iso tests we see on the forums, when we need higher iso, it's usually because the light levels have fallen and we're barely at the last point of getting the shot.
