And there is is irony....the 1Dx was to unify the two 1D ranges...the 1DIII and 1DsIII into a single body and a single range....but the 1DX came out at the price point of the old 1Ds range....if the 1DX proves to be nothing more than a full frame 1D series...then how much will Canon charge for their 1Ds replacement? Silly money I guess...
Whether Canon were genuinely intending the 1D X to replace both digital 1-series lines, or whether this was just FUD whilst they developed a high-res sensor for a 1Ds MkIII replacement, the outcome will be the same! (assuming this rumour is correct). With the talk of a Pentax 645D MkII, I'm not sure that there's quite as much headroom above the 1D X as there otherwise might have been, nevertheless I think it's safe to assume at least a $£€1000 premium.
