That's true, that's what I noticed too when I was selling my 24-70L. Even though MSRP for both lenses were about the same, because of all those people buying the 5D Mk2 kits then selling the 24-105L, the 24-70L was consistently listed for about $200 more.
I decided that the f/4 wasn't bright enough in low-light and indoors, even with IS, so I passed on it. Had the 24-70 for a year and a bit, wanted IS but didn't want to give up f/2.8, gotten the 17-55. Much happier now.
