More Info
I've recevied some more info about a possible replacement of the 50D/5D Mark II.
The source says a new xD camera is imminent.
The DSLR lineup from Canon will be as follows.
1000D / XS
500D / T1i
550D / T2i
7D
5D Mark II
3D (?)
1D Mark IV
1Ds Mark III
There could be some truth to this, if the price of the 7D is cut like the 5D Mark II's has been.

Will prospective buyers of the 3D have to take a test on the history of Canon film cameras, to ensure that they have the required knowledge to buy one? I own an EOS-3 owner and agree with AAJ. Naming a camera the “3D” is a really bad idea that is not “just to be expected”.
I really do love Canon but they have let me down with their image quality tough Nikon has been letting me down with their low mp’s.
I love the 550D’s 18mp censor but it’s low light capabilities compared to the D90’s and it’s high ISO noise capabalities are just not as good. It also has a very slow 3.7 fps compared to a also slow but reasonable 4.5 or 4.7 whatever it is on the D90.
And video ohh my. D90 SUCKS on that. Canon really blows that one out of the way the 550D is a mean machine if you love making videos. but focusing still sucks. I have invested thousands of euros and dollars on my equipment so I bet you Canon will be bringing out their 60D!
or else.. would you like to buy some of my equipment?

You are pay the price for the APS-C 18 Mp sensor.
If you are a pixel peeper, You need extremely good lens to make full use of the 18 MP sensor. You pay for poor High ISO performance regardless what lens you are using. Try shooting with f4 to 6.3, you may get a better picture due to the minimizing of the diffraction effect. That is why I bought a used 40D instead of 7D( which I have been waiting for 2 years after my 20D is having a slight intermittent shutter release problem). I do not care for the 50D and the 7D also disappointed me in High ISO performance.
Having owned both the 5D2 and 1Ds III I can tell you that the 5D2 is not nearly a 1Ds III, not even close. I know everyone is wanting a 1Ds without the vertical grip and be called a 3D. I want that too but it is not going to happen. If Canon ever had any intention of releasing a 3D it would have happened already.
Hence my point – you need an amount of shift roughly equivalent to what the human eye sees. The TS-E 17mm offers something like 12mm, but I don’t think that’s enough. And then you’ll have to deal with the distortion from the lenses, which seems to require stretching the image out, more as you get to the end in the direction of the shift (both pulling it out to the end but also, possibly, perpendicularly to the direction of the shift – as I indicated earlier, shifting only keeps lines straight; it is not a surefire end to the “falling away” phenomenon; it’s very hard in practice to keep all your lines straight when using the shift).
You realize this comes at a grievous cost to quality. Looking at one of my shifted images, you’d have to interpolate nearly one full pixel for every one you have in place at the end of this shift.
A split lens would work for the purpose of creating a stereo pair, perhaps with a pair of internal shutters to block each lens in order. I think in this case the internal IS group is a needless complication, perhaps; it seems more a surefire thing either to aim the outer pair of lenses at a common inner group, or perhaps to have a “fixed” pair of inner groups moving in unison that continue to focus each outer lens more directly on the focal plane. I imagine that the image plane might not end up completely parallel to the sensor in such an alignment, however.
And we’re still left with the problem of the snaps not actually being simultaneous. Perhaps if there were a way for one group to shift the wavelength of one side of the image, and then correct for that later…but that would essentially be a fancy version of red/blue glasses and would come with quality ramifications. Two-sensor solutions make the most sense, but nearly disposable P&S cameras are taking over that segment already.
