50MP is an important threshold. Because you then can sample 4 Bayer pixels into one preprocessed color pixel without loosing on any potential 12MP resolution.
In other words: 50MP cameras can provide for perfect 12MP workflows which, I do agree, suffice for many applications.
A preprocessed 12MP raw file from such a camera would be very similar (a bit better because of much better noise characteristics and DR) than a raw file from a true 12MP Foveon sensor w/o AA filter. So, it would be sharper than a native 12MP raw.
Therefore, we all will feel the buying addiction when those beasts come out
Nobody then will want to buy a 12MP camera anymore. And lesser pixels equal less noise is a false myth. Personally, I believe 2012 will be the year of 35MP FF cameras and 50MP+ then is only one more generation ahead (if Sony would have scaled their 24MP APSC sensor it would happen already now; but I hear they use the pixel pitch of their 16MP APSC sensors rather than their 24MP sensors for their pending FF offerings).
