I love my sigma 50mm/1.4 optically. And the bokeh is superb. Unfortunately I've found the AF to be unreliable at distances larger than a few meters. Unless the AF has been fixed in later versions (I have an early copy), I would not recommend this lens.
Unfortunately, the sigmas I've tried have not been as reliable with AF as canons (in general). Unfortunately, because their lenses are often optically very good.

The sigma 135/2.0L is already pretty cheap. How cheap do you want it? You can grab one for $800. A Sigma 135mm would have to be 400-500 for me to even consider it over the 135L.

At the moment, Amazon and B&H sell the Canon 135mm f/2.0 L costs ~$970, so $500 sounds good to me. If Canon can make a good 85mm f/1.8 for $400, and outdated 135mm f/2.8 for $500, I would think $500 think Sigma can make a good 135mm for $500.
I can't make the photography equipment I buy tax deductible, my last name isn't Rothschild, and I'm not a drug dealer, so sometimes I'd rather save $500 on a lens than bling it with a red ring w/o compromising on quality.
Etienne:
telephoto is not critical for me, but if Canon comes out with a 135 2.0L with IS, I'll be sorely tempted

Reasonable in what way? Fair? here's a quote:
the Sigma 50mm f/1.4 EX DG HSM Lens has proven very inconsistent for me in the focus accuracy department.
I have thrown out as many as 70% or more images from a single shoot of over 100 non-action, wide aperture shots because they were very OOF (Out of Focus). These were not even close-distance shots that are typically most challenging for shallow DOF lenses.
Though a higher percentage of the mis-focused shots were front-focused, a significant number were back-focused as well. Therefore, focus calibration is not going to help this lens.
I think that this lens would be better suited to a crop frame camera, I have sold the Canon f1.4 50mm in the hope of a replacement which I think will be a vain one as Canon haven't released a non L FF prime in too many years.
The Canon 135mm f/2.8 (which I do have) id not really a fair comparison with the 135mm f/2 because it is a specialised lens with an adjustable soft focus effect, even if I had the 135mm f/2 I'd still keep hold of this one.

For my copy, AF works better for close distance shots, strangely enough. The AF actually only misbehave on distance shots (> a few meters).

Why do would the Sigma 50mm/1.4 be better on a crop?
