Sony has just announced its new generation of APS-C cameras (Sony A77 - the flagship). The main part - brand new sensor that has 24 MPix. That's quite a handful. Well, probably it would be better to put it like this - that's quite a disk-full. I think that for my personal purposes 16 MP sensor (20-25 MB per RAW file) is just enough.
So, here you have it - in my opinion, for my photography 24 MPix is too many, 8 MPix too many to be precise.
Of course, beside the improvement of pixel count and sensor technology, new introductions have other interesting things. It would stand to reason that when other manufacturers including Pentax will show their new models they will have better metering, faster AF, etc. All of this will be available for a proper price, but if I would want a better AF (I still find AF of K-5 to be sub-optimal) I'd have to adopt this sensor with all its mega-pixels.
Suddenly Ricoh's modular systems looks quite brilliant. You want better algorithms - you get a new body. You want some special lens - you get this special lens module. Modular! Flexible!
Well, one can only dream and wish so much...
