In the next few weeks Sony will announce a new 20MP APS-C sensor in their upcoming a58 camera. It remains to be seen if Nikon will decide to use this sensor in one of their future DX models. For now, the D7000 replacement is rumored to have a 24MP sensor. Out of the four Nikon DSLRs announced last year, only the D800 and D600 sensors was made by Sony (the D5200 sensor was made by Toshiba, D3200 by Nikon and the D4 by Nikon).
