If it's the 2nd case, then 1D-C owners would have to come to a service facility for each and every firmware upgrade in the future, which I somehow doubt Canon would do.
If there are only a relatively small number of 1D-C cameras sold (lets say 1000s or at most 10s of 1000s) then the number that need to be serviced by each service center is going to be small.

Worth pointing out that Canon opened a service center in Hollywood specifically for the Cinema EOS line, to cater to the needs of cinematographers with Canon gear.

I can't believe there isnt a 1dm3 update also, that is more likely to be used with a 200-400 than a 1ds...
Maybe Canon doesn't want to touch the 1DIII AF system even with a 10-foot pole...   :o

In fact, there is an equivalent update for the 1DIII.

EOS Bodies - For Video / Re: Bag for 60D - what should I buy?

Someone also mentioned the Lowepro bag finder. It may work in some cases, but when I entered what I wanted to put in the bag, it provided choices that would not work and omitted many that would. I found the Pro Runner 350 AW by looking through their site the old-fashioned way.

Even that's a challenge, sometimes.  Camera bags are one area where going into a brick-and-mortar shop is a great idea.  Bring your gear, put it in the bags, see what fits and what doesn't.  Try the loaded bag on for comfort. 

Online descriptions can be misleading.  For example, someone above mentioned the Lowepro Primus AW - I bought one, used it once, then sold it.  The desciption includes the statements, " It is made to carry a pro digital SLR or DV camcorder outfit with accessories, and personal outdoor items," and "Side zippered pocket allows for fast access to camera and lenses."  In Lowepro parlance, 'pro digitial SLR' usually means a 1-series or gripped body. What the description doesn't state is that a gripped body cannot possibly be removed or inserted via that quick-access side pocket, and even with the grip removed from my 7D, it could be pulled out ok but was very hard to put back in without removing the pack and opening the main zipper. 

I assume you are mounting the GP-E2 in the flash hot shoe. If so the GP-E2 should communicate with the camera through the hot shoe without a cable.

Perhaps the OP is using a flash in the hotshoe, and therefore needs to attach the GP-E2 via USB?  Otherwise, there's no need for the USB cable with the 5DIII...

Intended for mobile phone cameras...  Worth noting that sometimes these technologies do not scale well, so what works for the small sensor of a cell phone may not be practical for a FF or even APS-C sensor.

3. The reason will be marketing (6d<5d3)  and production, i.e. more tolerance on the 6d and cheaper components ...

The 5DIII has a more robust shutter to support it's higher frame rate (more durable, too - rated for 50% more actuations).  The shutter in the 6D moves slower, so the Xsync is lower.  Same reason the 1D X has a 1/250 s Xsync - shutter is more robust and moves faster than the 5DIII's.

... now and on the website the 1.2.4 firmware is only found for windows and not mac..

It was there for Mac OS X v10.8 when I downloaded it yesterday afternoon.

They're $130 cheaper than the launch price (at which I bought my first one), $50 cheaper than the pre-rebate price (at which I bought my second one).  So, the $500 price (at which I bought my third one) is a pretty good deal...

I don't trust DxoMark and the scores that they assign to lenses....

Look at the Canon 600mm F4 while mounted on a 5D3.... Dxo rating is 26.

There are higher rated Canon lenses you can buy....

Canon 50mm F1.8 while mounted on a 5D3..... Dxo rating is 28.

That's right.... the cheapest lens Canon makes is rated higher than their most expensive lens.... OK people, who wants to swap their 600F4 for my 50F1.8? Even though the 50 is a better lens I'll swap you even....

This is my earlier point - their Scores are useless. However, their Measurements are generally useful.

Sekonic is probably closest to an industry standard.

Mikeal, you were asked a direct, specific question:

Please explain.  The Canon MTF charts have both thin and thick lines.  I thought the thick lines corresponded to 10 lp/mm and that the thin lines corresponded to 30 lp/mm.  We're not comparing thick from one lens to thin on the other.  Unless you are saying that what the thick and thin lines represent (x lp/mm) varies depending on the Canon lens focal length.  Does it?

You respond with:

If you look at common  motive the 10Lp/mm  frequency makes up 57% of the total assessment, while 20 lp/mm counts for 29%, and 40 lp/mm 14%.
So I think both Canon and Nikon knows what they are doing when they calculate what a 500mm or 600mm often be used to.

...which is a tangential response that basically repeats an earlier post but does not answer the question being asked.

what we know is that Nikon has taken big market shares  from Canon and where Canon  few years ago was the  the dominant company

Who's the 'we' that know this? Does it include anyone but you?  Can you provide some data to support that claim? 

Here is the summary as of ~7 months ago (pasted from here):

In 2007, Canon had 43% of the dSLR market, Nikon had 40%.  In 2010, Canon had 44.5% of the dSLR market, Nikon had 29.8%.  So, over years while Nikon was bringing us better sensors than Canon, Nikon was losing market share while Canon was gaining it.  Ok, fine, but that's 2010.  What about this year?

In 2Q2012 (by calendar year, they report it as 1QFY2013), Nikon had an 18% y/y growth of unit sales of dSLRs and lenses.  In 2Q2012, (they report by CY, not FY), Canon had a 47% y/y growth of unit sales of dSLRs and lenses.

Where's this 'big market share' that Canon has lost to Nikon, and when?  I look forward to your analysis...and the supporting references.

EDIT: Worth adding that about a month ago, Canon issued a press release stating that they had maintained the #1 position in the dSLR market for the past 10 years, through 2012. But maybe you're better than Canon's lawyers at checking facts, Mikael.

So, if that ratio holds, 50 million of those 90 million lenses are most likely the variants of the EF-S 18-55mm kit lens.
That is nothing to be proud of.  :-\

You do realize that those with an xD or xxD body and more than 1-2 lenses are a minuscule fraction of the Canon dSLR user base, right?    ::)

I can't believe there isnt a 1dm3 update also, that is more likely to be used with a 200-400 than a 1ds...

Maybe Canon doesn't want to touch the 1DIII AF system even with a 10-foot pole...   :o

I wonder what is the lens by lens breakdown of that 90 million?

Well, in 2011 they had manufactured 70 million EF lenses and 50 million EOS bodies.  So, if that ratio holds, 50 million of those 90 million lenses are most likely the variants of the EF-S 18-55mm kit lens.
