You’re not talking about the vast majority of work out there, which is, at most, a double page spread at 150lpi, that reauires 266 dpi in the image file. That’s even an extreme for most work. We did a picture of Bombay Sapphire that went on the side of a skyscraper (Special printing, and numerous prints). That was over a dozen stories high. The original image was just 8mp.
I am assuming you're talking about the GIN (i.e. a nice tasty drink that goes VERY well with tonic and some slices of lime or kiwi!) ... The Microsoft sign I was talking about earlier from 2003 was 400 dpi or about 200 ppi but from the distance it looked GREAT! I vaguely remember it was an ad for Windows Server 2003. In this case it was a BMP file (cuz MS invented the BMP format!) so they made it 32,000 by 32000 pixels to showcase the strength of Microsoft software in publishing and multimedia!
I should note it was an RGB file and NOT a CMYK because BMP does NOT support CMYK. THey probably turned SPOT colours into RGB colour and let the printers reconvert back to CMYK. Anyways, the gist of my earlier comments is that PPI and DPI at high enough numbers WILL LOOK MUCH BETTER than low dpi/ppi.
And since MANY fashion/product photographers work TEND to end up on 72 by 48 inch poster boards or in 2400 dpi glossy magazines or books, they NOW NEED 50 megapixel to 100+ megapixel cameras. AND for Canon, that's a 2 to 3 billion dollar worldwide market right there in the first 2 to 3 years of introduction!
They ALREADY have very large sensors in the 250 megapixel range and their LARGEST sensor is a 440 megapixel monster used for satellite and astronomical imaging systems. Doing a 70 mm 100+ megapixel Super-Medium Format is CHILD's play for Canon's engineers! They just have to SCALE UP the body of the 1Dx Mk3 by 1.5x on all dimensions and put in Global Shutter at 20 fps and they will HAVE A MEGAPIXEL MONSTER winner of a camera! I'm pretty sure they would 10,000+ of the $20,000 US bodies in less than two years and another 2 billion+ in lenses by the 3rd year! After that they could trickle down the technology to an FF 150-to-200 megapixel monster 5D-like RF-mount at $5500 and it will make a fortune for them! All the wedding and studio portrait photographers would snap it up within minutes of pre-orders coming online!
