I get the impression from your various responses to answers to your initial question that you really want to buy a 135L, so why not just go ahead? If you find that it doesn't add anything useful after all, you'll likely be able to sell it for around what you paid for it.
I would be surprised if you didn't find the bokeh better from the 135mm wide open than from your 70-200 wide open, but the same is true of your 100L, and, as privatebydesign points out, the fact that you can get much closer to your subject with the 100L makes it potentially an even better blur-machine than the 135L - depending, of course, on how far you want to/can be from your subject. It may be that the 135L provides better bokeh on objects farther from the subject - I've not done any direct comparisons myself, but you can probably find some online if interested - and the 135L avoids the hunting that you can get with the 100L, albeit at the expense of focus distance and IS. But given how context-specific these perhaps rather fine differences are, it's much better to compare them first hand if you can. (I've ended up with both the 100L & 135L, don't expect to sell either one, and prefer the 70-300L to the 70-200L 2.8, but that's just me.)
Again, fair comment. I see the the 100L and 135L serving different needs, so perhaps I will pick it up.
