To the first, not really, if you know how to use your equipment and have a basic grasp of post processing as I demonstrate, very large high detail and quality prints are more than possible with the current sensors. More MP might be nice, but it isn't, generally, needed, and the disadvantages of always having more can vastly outweigh the advantages of having it, just ask any D800 owner about their computer processing times and storage requirements!
I have a pretty solid grasp of how to use my equipment, how to post process, I own a 44" printer, I shoot professionally and I also exhibit in galleries. I can tell you from years of experience that printing large depends on what you mean by "large" and how acceptable the results are depends on the subject matter. I've made 6-foot tall exhibition portraits from a single 5dII file. But I would not print a landscape photo (or a cityscape photo as is my case often) with lots of fine detail in it larger than 20x30 at most from a Canon camera (and often I find 16x24 unacceptable) because the fine detail falls apart. So it's not quite so simple.
To the second, it depends how you look at it. But no, I have the print and if the crop is 7" wide on your screen then it is the same size as the same detail on the print.
As for my methodology, I upscaled the original 21mp image to print at 240, anybody saying you need to print big prints at higher resolutions just isn't actually doing it. I then wanted to show an actual life sized (as close as different resolutions of monitors will allow) crop from that 31"x47" print. To do that I measured my screen and a 700px image in the forum, it is 7" wide on my 27" monitor, I then cropped a 7" section out of my print file and downsampled it to 700px. This means it is an accurate reproduction of my print life sized if you are displaying it at close to 7", if you have a calibrated screen all the better.
An image displayed on a monitor is not quite the same as an image printed on paper. In any case, if you upscaled your print to 240ppi, then a 7-inch crop should be 1680 pixels across.
But again, just because you can print a portait large and it looks good doesn't mean a landscape photographer shooting with the same camera can print a photo large and have it look good. So I'd advise against making blanket statements about others not knowing what they're doing just because they say they could use more resolution.
I agree, what is large? I would venture that you and I, regularly printing over 24", are in the extreme minority, from my experiences I would say 80% of photographers don't print at all, to them large is a 60" TV with the groundbreaking resolution of 2MP. Some might have spent a fortune and moved up to the latest and greatest 4K, 8MP, big whup!
I would also venture to say if you are a true landscape big print professional (I am not) then basing your captures on a single 135 format capture would be cavalier in the extreme. Even with a D800E.
There will always be a few people who push any metric of any camera design, I wasn't stating that nobody needed more MP, I was pointing out that the numbers we have can be used to very great effect and I don't believe many people
need more the vast majority of the time, me included. I was also pointing out that if you don't need it regularly, the downside of dealing with it all the time becomes a big negative.
I believe part of Canon's marketing leadership is based on them knowing what they are doing, to do that they know a trick I was taught many years ago by my mentor, don't give people what they say they want, understand what they want and give them that. Most of the time, as the marketshare demonstrates, Canon do deliver what people actually want.
To me the 5D MkIII is probably the greatest mass market high end SLR ever made, it will probably be the most appropriate camera for most users, ever. I believe when it is replaced many of the features will be market driven crap people think they want but then rarely, if ever, use. Mixed in with those spurious distractions, sure a bit more DR will be nice, though none of the bleaters ever shows an optimally exposed real world image where the one stop lower Canon DR has ruined their image. Sure a few more MP would be good so I can crop 80% instead of only 50%, well use a 7D instead, that is what it is there for, if you want a 40+MP FF sensor so you can crop to "extend" your lens, you already have it, for a bargain price!
My tale is more a cautionary one, I am no King Canute, we will get more MP, we will get more DR, we will get WiFi and GPS etc etc, and nothing will stop that, the DSLR market will continue for a time yet. I just think we should be careful what we ask for, if we shout too much then they might just give it to us. I just don't want to be bothered with 40+mb RAW files, every, single, shot.
As to my crop, it was 1680px wide, but if I had posted it at that it would have displayed nearly 17" wide, that is not what I wanted to do, I wanted the detail to be life sized in relation to a 47" print, to do that I downsampled my 1680 wide print file crop to 700px wide to display at the correct size in the forum. I don't understand why that is such a difficult or complicated idea for you, a big printer, to get their head around, it is obviously a failing on my part to be clear.
If, on your monitor, my crop is close to 7" wide you are looking at a life sized proof of a small section of a 47" print from a single 21MP capture. I could post the 1680 crop and then people could print it if anybody cares enough, but that would only be relevant when printed, it would not be relevant as a displayed image. Yes my crop has lower resolution than the print file but because of the vagaries of display and print pixel requirements you are pretty much seeing what a 47" print looks like.
