In addition to analyzing the use of Sony sensors in Nikon DSLRs, Chipworks has also published an article that explores Canon’s full frame sensors. It’s quite technical, but the main points can be grasped without understanding the terms being thrown around:
On the process side, the 1D X is remarkable in that Canon continues to stay with the 0.5 µm process generation it has used for every APS-C and FF device analyzed. While the use of a mature fab likely gives Canon a competitive edge via lower manufacturing costs, it may also weigh heavily in its product development [...] Given the geometric constraints of 0.5 µm design rules, Canon seems content to hang around the 21 Mp resolution for recent FF sensors through the use of shared pixels [...]
So, back to the rumors of Canon allegedly readying a high resolution competitor to the Nikon D800. Will Canon finally move off that 0.5 µm generation? It is worth noting that September 2012 marked the 10 year anniversary of Canon’s announcement of the world’s first CMOS FF sensor, the EOS 1Ds [...] every Canon FF sensor analyzed since has used the same 0.5 µm design rules. It is a credit to Canon that it has remained competitive by continuing to optimize its pixels fabricated in a relatively mature process.
What they’re saying is: if Canon wants to continue fighting in the megapixel wars with Nikon and Sony, it’s going to need to shake things up a bit in its sensor department.

It has only been a month since Sony announced its latest flagship full-frame camera, the A99, but rumors are already beginning to emerge regarding the company’s next top-of-the-line offering. sonyalpharumors writes that Sony has reportedly marked sometime between May and June 2013 as a tentative release date for its next high-end full-frame:
The camera will be more “photographer” oriented. There are currently a couple of different prototypes. One we heard of has a 36 Megapixel sensor (same as Nikon D800) and built-in vertical grip. Priced well above the current Sony A99. A second prototype has a new 50 Megapixel sensor which goal is to go as close as possible to a “medium format” quality.
The new camera wouldn’t be intended to replace the A99, but would instead become the flag-bearer by creating an entirely new tier in the Sony lineup. If the latest rumors pan out, then 50 megapixels may soon become the new standard resolution for flagship DSLRs; Canon is reportedly working on its own high-res (46MP) camera.
Update: Reader Scott Hutchison reminds us that back in May, there was a rumor that working on a “A1S” camera with a full-frame 36x36mm square sensor. Hmm…
If you thought the megapixel wars were dying down, think again: the upcoming Nikon D800 is rumored to shoot at a whopping 36 megapixels. If true, it would be a crazy leap in resolution from the 12.1 megapixel D700. The rumor originally showed up last week on Japanese site digicame-info, and was “confirmed” today by Nikon Rumors. In addition to the model name and number of megapixels, some other details include: 4fps shooting, 1080/30p video recording, support for both CF and SD, and a shutter rated for 200K shots.
Nikon Rumors also states that the fact that specs are beginning to leak suggests that the camera may be announced in the next month or two.
