although if the rumor about the 21.5 is true, they would have to do something to the 24", because they would be lower spec than the 21.5
I agree. The fact that they are putting a 3.06ghz C2D in the 21.5" iMac leads me to believe that they are going to have to completely re-do the 24" iMac this cycle or next cycle. Otherwise it won't sell much at all.
