If I remember, some of those NASA Mars photos were 1mp RAW files, though the chip was quite large. It does seem finally the MP wars have quieted down some. Now if the dSLR makers can focus on better chips, less banding, less noise, longer lasting cameras........oh that's right, that would cost too much money.
