I'm a bit surprise that the 24f2.8 has IS and the 24-70 does not; i'm also a bit surprise the 24f2.8 was redesigned before other lenses given its relatively good performance. I've not check the schematics but is it a totally new design ?

Form of MTF curves (computer generated) of new vs old 28mm&24mm suggests that they are very close relatives,
probably just like 18-55 & 18-55 IS.
>And let's not forget: both got rid of the DC motor and feature USM now. No more "sneeeek, sneeek"
Don't forget about generous price bump <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='' />
