You're quite right there neuroanatomist. But no one knows if canon will really release the 24-70 IS so probably the best thing to do is just wait & see until the time comes. But I say that will be a big hit if ever they'll gonna release the IS version.
cxr,
You need to decide first the conditions you will be shooting under. I have had the EF-S 17-55 f/2.8 for a year and I love it. I have had zero problems with it and a very high keeper rate. I just bought the EF 24-70 f/2.8 and am still adjusting to using it. Without the IS I have discovered that I am not as steady as I once was. Still, I do get great images with it. Since a lot of my pictures are indoors without a flash a wide aperture is a must for me. I toyed with the idea of the EF 24-105 f/4 mainly due to the IS, but I would not be able to take many of the sports photos like the one below. Eight year old girls move quick!
In my recent poll, it was stated that I am well covered in mid-range zooms, but they are what I use most. I decided to try the EF 24-70 f/2.8 because I wanted the little extra reach. To me it is worth it. Furthermore, I looked into renting the EF 24-70 f/2.8 and the rate is @ $200.00 for a month. My feeling is that I can use it for a few months and should I decide I do not want it, I can sell it for @ $200.00 less than I paid and basically break even. I will most likely keep it though as my goal is to also get a full frame down the road, I am currently looking at the 5D MkII. I am also seriously considering adding the EF 24-105 f/4 for outdoors. I know it is a lot of mid-zoom, but again, it is currently my most used range and I want the best images I can afford.
To directly make a suggestion to you, if you need to stop action in low light and you are going to stay with a 1.6 crop camera, I would go with the EF-S 17-55 f/2.8. If you are thinking of going full frame and need a wider aperture, then the EF 24-70 f/2.8 is for you. Also, you may want to keep the crop body as a second shooter. I have a 50D and it is better for sports than the 5D as I can shoot more frames/second.

Canon 50D, EF24-70mm f2.8L USM, 1/125, f/2.8, ISO 1600
As you can see, not only would I have a problem with subject movement I am at the end of my comfort zone for ISO. A f/4 would not work here for me. If the 24-70 goes IS, I will probably be in line for one, and sell my non-IS to help fund it. [<)] Plus, I have to agree with Brendan, there will be a near doubling in the price.
Good luck choosing, I know how tough it can be. []

This photo completely contradicts what you say: for stop-action, and this particular photo, IS is useless. Your shutter speed is fast enough that IS isn't a key benefit. You're already at 1/focal-length for shutter speed. That's not to say that IS wouldn't be helpful for other photographic tasks and situations, but stop-action requires shutter speeds that "override" hand shake.

IS is a valuable asset for hand held video work and I would gladly trade up for it (:

<p style="margin-bottom: 0in;"]peety,
<p style="margin-bottom: 0in;"]<span style="font-style: normal;"] I
am sorry if I did not state it clearly enough, but my point,
particularly with that photo and the many others like it I take, is
that the f/2.8 is immeasurably more valuable than the IS would be to
me. I must have failed to make it clear that had I tried to take that
photo with the EF 24-105 f/4 I would have had to use much higher ISO
and much slower shutter speed, resulting in an undesirable photo.
With f/2.8 to freeze the action I am generally at ISO 1200 – 1600,
which is as high as I care to go. My IS comment was not for action
photos, but for darker venues with much less movement, like the
school play, to compensate for my “hand shake” as you suggest. My
wish, like many others, is to have both f/2.8 and IS. <span style="font-style: normal;"]I
have taken about a thousand images with the 24-70 in the couple of
weeks since getting it and I am very pleased with it. I am getting
what I hoped to get from it.
<p style="margin-bottom: 0in;"]
<p style="margin-bottom: 0in;"] <span style="font-style: normal;"]As
far as getting used to it, it is little adjustments like the focus
and zoom rings being reversed from my 17-55. I have to remember which
I am using when I first start, but once I am going it is not a
problem.

hi guys! any update if this lens is really coming out? i started to save to get my first L lens, either the 24-105 or 24-70 but if this one (24-70 IS)is reallycoming out, i thinkit will be a killer lens.
Go pop your head into the Canon Rumors site and read away.
When Canon announces something, they announce something. Until they announce something, they don't announce something. They haven't announced this lens, so they aren't releasing it. Yet. Today. But tomorrow could be a new day.
No one here has connections into Canon that allow them to announce things before they are public. If they had those connections, they'd likely lose them if things were announced before they were public.
