Announced in August 2007, The Canon EOS 1Ds Mark III Pro DSLR set the standard high megapixel DSLR's with its 21 megapixel full frame sensor.
However in 2008, Sony launched a 24 megapixel A900, Nikon launched the 24 megapixel D3x, and Canon released a 21 Megapixel EOS 5D Mark II, which offered a wider ISO range, and many claim a higher image quality.
For Canon to get back on top, the high resolution pro body desperately needs updating: a Canon EOS 1Ds Mark IV could be here as soon as 2009.

CR is suggesting either July 12/July 13 or July 19/July 20 as the probable date for a DSLR announcement, which will be either a 60D or 3D (but no the 1Ds Mark IV).

Planet5D is reporting a tip that Canon has released some prototype Full Frame HD-SLR Cameras to select photographers in Europe, which shoots RAW Video.
The claim the source of the information is new, but they believe reliable.
The next two Full Frame cameras expected from Canon are the 1Ds Mark IV and the 5D Mark III (although rumors of a 3D won't go away either).

In an interesting comment (thanks) from one of our previous sources, we hear that some people at Canon are saying thet the 1Ds3 still has over a year's life, and that Canon will not be releasing a pro camera in 2010.
Nikon doesn't currently have anything over 12 megapixels for under $8k, so while there is not huge pressure there, 2011 does seem a very long wait.

According to CR, the Canon 1Ds Mark IV is on track for a Photokina 2010 launch, with a whopping 32 megapixels (or possibly 28 mp), ISO 100-6400, 5 fps and the same body and AF system as the new 1D Mark IV.

NI has been going through Canon Patents, and came across a mention of a 7,680 row by 4,320 column sensor - about 33 megapixel "full color" sensor (3 layers, foveon style).
Patents do not necessarily lead directly to products, but a 33 mp Canon 1Ds IV would be an interesting beast.

NI has a detailed commentary from a "long time trusted source" on the Canon 1D Mark IV prospects. They claim that the high price of the D3x has lessened pressure to release the Mark IV, which was originally planned for August 2009. The August 2009 date is now unlikely, since 1Ds Mk 3 sales remain strong too.
They also claim Canon have a range of sensor choices here, up to 39MP, and that the delay also allows the new AF system to be considered - one of the main weak points of the current 1D series cameras. Since AF is a key factor in 1D4 timing it is also important to the 1Ds4 too.
Allegedly Canon have two release windows in mind, either January/February 2010 or August/September 2011 (3 years).

CR has received an email stating January 2010 is the date:
“Yes, it has been delayed until January now, this is the second time this has happened although this time not due to a technical issues but more marketing. If everything goes to plan (which hardly happens to be honest), January will be a killer month for announcements:
1Ds Mark IV together with the new duo of high end lenses. The 70-200 2.8 IS II and of course the 24-70 II IS.”
They rate it as CR1 - their lowest rating - click the source link below for their response.

DSLR Magazine (via google translate) is claiming that two new high-end pro Canon DSLR's will be announced this year.
They expect more megapixels for the 1Ds Mark IV, claiming Canon are "focused" on competing with Medium Format cameras (Nikon compared the D3x to medium format at its launch also).

"I have recently been into one of the Canon authorised service centres to pick up my recently cleaned EOS1ds Mk II. I got into a fairly detailed discussion with the guy about the relative differences between the slightly older model 1's and the newer models (say the 5 mkII). His view was that the 1's were 'losing ground' in terms of technology against the newer models - the 5 MkII and the 50D.
He said that while the 1ds Mk III was still an awesome body, Canon were set to announce a whole new revamp to their top of the line model - and possibly other in the 1 range especially after Nikon announced the arrival of the D3X recently
He said the announcement was not due to be made until april at the earliest - but more realistically June. "

NI is reporting that the 1Ds Mk IV is slated for a February launch. They are also reporting that the 1Ds Mk IV will not be yet - later in the year, and the Feb announcement will refresh the lower end of the DSLR range.

Canon Hong Kong have announced a price drop for both the Canon 1D Mark 3 and 1Ds Mark 3, by about 10%.
Could be an indication the replacements for both these cameras are coming. Could be currency fluctuations. Could be just trying to clear excess inventory (although a temporary rebate would be more likely then)
See source link below for press release.

According to NI, Dell has told at least one customer that it would not lease a Canon 1Ds Mark III to them (even though they had two in stock), because they are at the end of its product life cycle.
They would however lease the Canon 1D Mark III.
As NI points out, the expectation for a while has been that the 1D Mark III would be replaced first (as a response to the Nikon D3 combined with recent rumors of an 'N' version), so the 1Ds being replaced first would be a surprise to a lot of people.
That said, in terms of image quality, the Canon 5D Mark II does in some ways obsolete the 1Ds Mark III (unless you are going to take it anywhere damp/humid - see Canon 5D Mark II Problems).
Either way, this is an interesting piece of information.

Northlight Images are quoting one of their long-time sources suggesting the launch will be delayed to later in 2009:
" Is it the combination of the economy and the less than enthusiastic response (in some quarters) to the Nikon D3x that makes a launch somewhat less imperative? That or a chance to test the new AF a bit more ;-)"
