The unit cost of these sensors is mostly based on size, not pixel count, so there is not much production cost saving in continuing to make something like the 22MP 36x48mm sensors. Also, the marketplace clearly puts a higher value on the new higher resolution alternatives (forum chatter to the contrary notwithstanding), so the older sensor models become less profitable to produce.
Digital has sold megapixels from day 1 and up to this stage it has worked.
Now whether it has anything to do with producing an interesting photograph is another matter and to me the megapixel race is only important to people who care about cameras more than photographs.
Right now the world is upside down and nobody knows where anything is going and I can honestly say that the cameras that I use for commerce are for different reasons than the ones I use for personal work.
For personal work I use a camera for the look, not the numbers or the detail. I prefer m p21+ over the p30+ because it has more texture, less smoothing, less digital in appearance, in the past I prefered the Aptus 22 to anything over 22mpx because I just liked the look processed in photoshop. For personal work in dslrs I prefer the original 1ds to my newer 3's just because I like the look.
Now for commerce it's different, I'll either use a p30+ because it has more detail or just because i'm in studio and I can, but truth be told for commerce I can shoot 99% of my work with a 1ds3 and everything is much, much faster and easier.
The information on this forum seems to be somewhat myopic as it is about digital cameras, not essentially photography, but in my travels and knowing the photographers that I do I find it amazing that so few own the latest and greatest digital back or even dslr. They will rent when required but at the high end of the photography world, I think everyone here would be surprised how many name photographers shoot film for personal projects. If they do shoot digital how many will use an olds 1ds1, or 2, even a 5d. I think everyone in the world seems to own a 5d.
The flip side to owning is renting and now that is easy as techs, digital companies and studios are falling out of trees looking for work. I just got an e-mail yesterday from a firm that will rent a tech, two p65+, two H series cameras and a computer station (with backps) on a 10 hour day at $1,400. That makes my brain rattle because I guess at retail price that is about 120k worth of cameras and computers for $1,400 a day and I would bet that is negotiable.
