Heres something that seems feasible. If they are re using the AF from the 1Dmk4 and the body from the 7D for the 5D3 (similar to the leaked pics) could this possibly them mean that we end up with a cheaper body.

Not possible. 

First - The 7D body/sensor/mirror/penta-prism are all built around a small APS-C sensor you can't just throw a FF system into a 7D body. 

Second - You can't just take the 1D4's (APS-H) Auto Focus and use it for a FF sensor, you'd lose a lot of the spread needed for an effective AF system. In other words the AF points would be confined to a shorter/narrower section of the sensor than they should be.

There was a clamour for the 7D AF and now the 1D4 AF is on the horizon everyone is after the 1DX AF - no pleasing people ::) ::)

Perhaps it is the 1Ds3 AF which is close.

  I personally doubt they'll be using the 1D4 system, they'd still have to redesign it from the ground up for a FF sensor anyway. I think it's much more likely that it will get a less robust version of the 1DXs 61 point. In that way they can increase the economy of scale by using essentially the same AF system in their entire FF line up.

No need to redesign anything. The APS-H 1D shared the same 45-pt AF module with the FF 1Ds from Marks I-III. So by extension utilizing the APS-H Mark IV AF module on an FF model would be a simple drop-in as well.

5D3 with 1dmark4 AF-sounds for my like selling my gear definitely and switching to Nikon finally. I wait with my Canon gear for better information. I heard a lot and read a lot about 1d AF, there's no match for even Nikon d700. Hope that's not true. I am really pissed about this AF problems in Canon. If they finally do something better and reliable in sport and studio I will stay, otherwise goodbye. Think a lot about this and that;s my decision maker

Ugh  didn't the 1d MK IV have issues focusing in low light.  I shoot weddings hope this  isn't true.  :-\

Is it just me or the latest rumors that mention specs are all reflecting topics that were just discussed on the forums?

Ummm...no.  The fact that they all have 45 points doesn't mean they're the same sensor, any more than the fact that both xxD and xxxD have 9-pt AF means they're the same.  In the case of the 1D IV vs. 1DsIII, although the 1D IV has a slightly wider spread relative to the total frame, it's physically a smaller sensor. So, if you just dropped it into a FF camera, it wouldn't have nearly as wide a spread. 

Granted, they could drop the 1D IV AF into a new 5-series body, and it would still have better coverage than the pathetic spread of the 5D/5DII AF points.

I've guided a wildlife photographer in the lowland neotropical forests of Costa Rica, he had a 500 f/4 L IS and a 1D mark IV, he never had that problem, routinely shooting between 1600 and 2500 ISO with great results !

Do you have any idea of what you are talking about? My 1D IIN has the same AF system as the 1Ds II, and yes, the 1D has more AF sensor coverage than the 1Ds.

I have to wonder if they're saying 'using the 1dIV AF system' is just an easier way of saying you aren't getting 61 points like the 1dx.

And lets be real here, someone mentioned an absurdly low price, like, $500 less the the current new price of the 5dmkii - Canon is already proving people are and willing to spend $2500 on a 3+ year old body with a crappy AF system.  Following that logic, even if all they did was an upgrade to a 7D like AF system, with better weather sealing, that alone would justify a more than the current model starting price.  And if it does have higher ISO, better DR, then yeah, you have a $3000 body, one that has enough upgrades to make it worth it, but, doesn't undercut the 1dx.

What you said may be true with the 1D IV and the 1Ds III. However, the older 1D and 1Ds have the same AF sensor size of 8x15mm (hope that I am not wrong here  ;))

Well thats good.  For some reason I thought I remember hearing the 1d Mk IV focused more poorly in the dark in comparison to the 5D Mk II's center point.  I have the 5D MK II and a 7D and I am really excited about a new AF system in the new 5D just need its AF  to perform well in low light.  May have to cough up the cash for a 1DX.

I couldn't find the AF specs of the 1D IV and the 1Ds III. However, Canon stated that with the 1D X, they expand the AF from 8x15mm to 8x19mm, so I assume that all older 1 series have the same AF surface, i.e. 8x15mm.
