I can see that Canon is paranoid that raising the bar with the 5D MkIII too high may poach sales of the 1D series, but the questions they should be asking themselves are where are Nikon going with the D800 and what will Sony next move with full frame be?
Why should Canon be paranoid ? Make no sense ! Nikon provides the same focus and metering on all their pro cameras (D300S, D700, D3S and D3X) and seem to have no "poaching" problem. Crippled is a word seldom seen on Nikon forums.
moreover if we are to believe the latest rumors the 1D series is merging and there will be no more APS-H sensors.
For professionals Canon would have:
1D mk5 - weather-sealed, excellent fps, full-frame, 45 pts AF
5D mk3 - not weather-sealed, decent fps, full-frame, 19 pts AF
7D - not weather-sealed, excellent fps, APS-C, 19 pts AF
Currently Canon is selling 5 cameras in that range (4 active models) so the distinctions were a little fuzzier for consumers who wanted a bigger sensor than an APS-C. Retrenching that back down to three professional grade cameras should help them focus their efforts more on making better cameras and meeting the needs of those distinct markets.
