So it would have a higher res than the 1Dx and just 2fps less? That is the part I don't get. I think the 7D is due for replacement, and these maybe the specs, but if they are, I don't see it getting here till mid next year. 1DX supply is tight still, eh?We're talking entirely different sensors though. For outdoor sports shooters who get bright sunlight, sure, there might not be a big difference. But then again, the current 7D would probably be fine for them (though the AF upgrade would be nice)
But for anyone working inside or in lower light, the 1DX sensor can shoot comfortably at ISO 12,800 and even 25,600, and the current 7D struggles at ISO 1600. Even assuming they get an extra stop out of the 7D sensor, its still well behind.
