There are already f/1.4 primes with excellent IQ at these focal lengths - the 24L II and 35L.
But the 24L II & 35L cost a lot more than ~U.S.$700
Sure they do...and Canon wants more of your money! So, if they can put a red ring on a lens and charge a premium, meaning more profit, that's what they want you to buy.
IMO, their viewpoint is that there are three broad categories of buyers out there:
- Typical consumers
- Enthusiasts / advanced amateurs / 'working' pros
- 'High-profile' pros
The first category will likely buy a Rebel/xxxD or 60D with a kit lens or two, and maybe a nifty fifty. The third category will be shooting 1-series bodies and all L-series lenses. The middle category is a broad one - xxxD, 60D, 7D, 5DII users, with multiple lenses, including zoom and primes. I think Canon would prefer to upmarket these folks - get them shooting on a 7D and/or a 5DII, and buying L-series lenses. The good quality, non-L primes are likely not in Canon's financial interest to update. Allow me to use your statement to illustrate that point:

I would be happy to buy 20mm f/2 USM, 24mm f/2 USM, 35mm f/2 USM, and possibly 28mm f/1.8 USM (all with IQ improved over the current non-L primes) for ~$700 each.
That's four $700 lenses, meaning you're (in theory) willing to spend $2,800. If Canon were to develop those four lenses, that would mean a significant R&D expenditure. From a financial standpoint, they'd realize more profit developing only two lenses in that focal range and charging $1400 for each. Thus, we have a 24L and a 35L, but no 20L or 28L.
I think Canon will attempt to polarize the market a little further, and we're seeing that in recent lens releases. They are concentrating on EF-S lenses and L-series lenses, and not releasing or updating anything in between.
