My mistake ... I assumed Canon had an 85 f/1.4 like everyone else.
Photodo appears to have repaired thir links. As you can see, wide open,
the f/1.2 is not particularly sharp. Quite crappy, actually for the $$$.

At f/8, no suprise, it is quite sharp.

From f/1.8 to f/1.4 is less than a stop. From 1.4 to 1.2 about 1/3 a
stop... not that much difference.
But, if Canon don't have an f/1.4 then I would be tempted by the f/1.2
too. I still haven't bought the 85 f/1.4 Maxxum that's been on my short
list for oh so long.

How's the old credit card situation? Maxed out?

Which one?

Well duh .... otherwise, I'd already have the 85mm f/1.2L on my
1DsMKII.

To nitpick. f1.2 is just over a stop larger than f1.8 but because of
extra light absorption exposure difference is calculated as one stop.
If like the movie industry, T stops were used, then exposure would be a
more precise calculation.
The glamorous f1.2 lenses are usually outperformed optically by their
humbler f1.8 brothers.

From first-hand experience, the f/1.4 is probably the best optically
for Pentax, superior to their f/1.2 ... and from what I've gathered from
others experience, the same holds true for Nikon and Canon.

Well, you could compare to the Nikon 85mm f/1.4 ... and then you might
compare the 100 mm f/2 to the Nikon 105mm f/2* DC... ;-)
*) 105mm/f2.5 and f/1.8 are good lens too, esp with a d200

If stitched panos are a major consideration (and I completely
understand the Wow experience they trigger), you should (have) at
least consider(ed) the TS-E 90mm. I can understand that the shift and
tilt controls seem a bit daunting for someone without prior training
in using view-cameras, but this lens (and its 45mm cousin) will allow
to make superior stitched panos. Coupled with extention rings, it
(they) also do a great macro job with the added benefit of being able
to control the plane of focus. Besides, its a better lens (image
quality) than the 85mm f/1.2 .

Here's a comparison below. I have the 85 1.8 and I prefer it to the 85
1.2 because it has much faster AF, is smaller, lighter, and cost much
less and I bet the 1.2 is not that much sharper. A comparison between
the Nikon 1.4 can be found at http://www.wlcastleman.com also.
