W :oW, Canon might present a 46MP Cam on the Photokina soon:

Pure pixel envy, when will it stop? 

I did like the 25 ISO part, but I know when I see the price tag and waiting list, I'll be back to waiting for the 70-D to get announced.

As for fps, it's something I watch and haven't been found lacking to only (cracks me up = only?) 3.7 while the 40-D is 6.5fps, I imagine how to move all that data through a processor and to a card fast enough to get the frame rate almost 4 for 46MP. I'm pretty sure this isn't a sports camera and 3.7fps in a studio should be fast enough?

Imagine this. 8MB image files per image, that's not RAW, but just a standard JPEG. So is that a 40MB RAW image? Did I figure right? 8GB card = 100 RAW images? 

Even my 5D mk II raw files can be in the 40MB are if there is plenty of detail in the image (like a fabric texture or similar).
I don't think the 46MP files would be much bigger, because the lens won't resolve much more detail, but maybe we'll get to the 60MB area.... 

And yes, I would certainly buy a 3D if the autofocus is at least as good as in 5D mk III and the price tag isn't totally insane.

And what of the 6D? Rumored to be a 22MP FF, entry level build?

I still wait for the entry level FF. I am not interested in body construction or speed; i want to use the camera only for studio work. For fast action , bad weather i have the 7D.

Back to the topic...

If the IQ of the newly rumored 3Dx ( which  i believe will be announced as a response to D800 )will be at least as Nikon D800 with a reasonable price, than Canon will hit the jackpot.
This camera is aimed to the landscape and studio photographers .... so, the speed is not a important aspect.
