I think we must remember that Canon is a business and they aim to make money. I realise that a fast high quality 50 is exciting to those of us who read here but I suspect Canon's research probably finds little interest, or at least not enough for them to be making it a priority.
Interesting that...
1) Zeiss did their research, and found there's a market for a 55mm f/1.4 Otus, and an 85mm f/1.4 Otus.
2) Sigma did their research, and found there's a market for a 50mm f/1.4 DG HSM Art, and an 85mm f/1.4 Art.
3) Tamron did their research, and found there's a market for an SP 45mm f/1.8 Di VC USD, and an SP 85mm f/1.8 Di VC USD.
4) Nikon did their research, and found there's a market for a 58mm f/1.4G AF-S, and an 85mm f/1.4G AF-S.
5) Canon did their research, and found there's absolutely no market for a 50mm f/1.4[L] IS USM. The 85mm f/1.4L IS USM does have a market, but it's whole different story.
The market isn't just people who would buy the lens within the first year. It's for people who want to buy OEM now, or their first camera next year, or switch from Nikon the year after that.
