<strong>Clues about Canonâ€™s Plan?</strong>
<p>I have posted that a new <a href=\"http://www.canonrumors.com/2010/12/the-canon-high-end-cr2/\">1D would come in 2011 before a new 1Ds</a>, that couldÃ‚ definitelyÃ‚ be a stop gap for a full frame pro body. Iâ€™m not sure if they solved the issue of not being able to do 10fps with a full frame sensor, 9fps was possible when the 1D Mark IV launched.</p>
<p>However, there is a part of me thinks Canon is still behind the APS-H sensor and thinks there is a market for it.</p>
You've also posted that the next 1D may be the merger of the 1D and 1Ds line. We're getting some wildly conflicting rumors.
At the risk of repeating myself, consider the possibility that (1) a fairly low resolution professional FF body will be introduced on 31 January, but it won't be called a 1D (How about 9D?), (2) the 5DMk2 and especially the 5DMk3 will replace the 1DsMkIII as the high resolution pro body, but at a substantially lower price, (3) the 1DMk4 will temporarily remain in the lineup as the cropped pro sports camera, eventually to be replaced by the 7DMk2 and (4) the 1DMk5 will be the 50MP FF merged camera with an HD-SDI port and capable of pixel binning, in-camera cropping and HD video with 4:2:2 color coding (look at the XF105 camcorder for inspiration).
Where am I getting this stuff? Some time last year, a rumor sprang up, I've forgotten where but maybe here, about a new model to be introduced in March 2011, with 14.5MP, and optimized for video use, with high DR and extremely low noise at high ISOs. Also, Canon strongly implied at Canon Expo (I think that was its name) that the 50MP sensor they demonstrated in multiple prototypes would appear in a future product.
Oh well, we'll know soon enough.
