24MP on an APS-C sensor is a little overkill this means a pixel density of 54MP on fullframe, so more than the D800.
I am not sure what the pixel size is on this sensor. I am pretty sure it is the same sensor as in the Sony Nex 7N.
There is a school of thought that says 12-18mp or perhaps 22 as in 5d mk 3 is the sweet spot for sensors.
But then there is another school of thought that says the more the merrier as it allows you to crop and still get excellent resolution.
This of course assumes you still have decent low light high ISO low noise performance.
These 2 goals have been conflicting for DSLR makers and Nikon as for the last several years pushed the first school of thought Presumably because that was the current technology at the time and all that was available to them.
5D mark ii proved that incorrect as 21mp at the time was class leading and still excellent low light high ISO performance.
Now the new Sony exmor range of sensors seem to push technology out where 24mp with low noise relatively high ISO performance seems available. D800 shows that matching the 5D mk 3 in high ISO RAW image performance (5D3 better in jpegs).
I have read where some believe full frame could go to 70 to 100mp.
Certainly the market tends to want more mp (even if misguided sometimes).
Its inevitable that larger sensors will become cheaper and eventually DSLRs will enter medium format size like Astrophotography has. The Kodak 16803 sensor is larger than 35mm. Kodak (should I say True Sense Imaging) has sensors up to 50mp and about 45mm square.
