A good reason for Nikon not to use the A900 sensor in a flagship

Canon, for that matter).

Interesting how you manage to have two assumptions in one sentence

Yes, but there is some evidence to back the assumptions up. If you
have counter evidence...
Of course, it could be that Sony and Canon are better at designing
sensors but have decided for some reason not to release their better

Bob, you keep on saying that on DPR, but if we look at Roger N. Clark. ( comprehensive work on Digital Camera Sensor Performance, it appears that (if I am not mistaken, any reader should visit clarkvision for details), comparing Nikon D3 and Canon 1DIII :

  • 1D III full well capacity is better than D3, even with smaller pixel pitch

  • 1D III Signal-to-Noise Ratio is better than D3, even with smaller pixel pitch

  • 1D III Read Noise is better than D3

  • 1D III Dynamic Range is better than D3

  • D3 Low Light Sensitivity Factor (high iso shadow perf) is better than 1DIII

  • D3 apparent IQ is better than 1DIII, mainly due to larger pixels.

Mr Clark also proposes another view of sensors, using megapixels * pixel pitch and so we have :
1. Sony A900
2. Canon 1Ds Mark III & Canon 5D Mark II
4. Nikon D3
5. Canon 1D Mark III

Maybe Nikon better designing is not that evident ?
