They have made drive option changes since release - if they make more they will be the same way - silent on apples site
They are not going to change the monitors any time soon they just came out with the new monitors for the Imac last year,my guess is this will be the standard for the next several Imacs
I do expect to see the existing 27 inch Imac screen modified tobecome the standalone monitor replacing the older standalone model.

With the new MacBook Air, they lowered the price of SSD, the same could happen with a Haswell based iMac. Also the new SSDs appear to be faster and hopefully the next iMac would have the same improvements.
The display is not that much different that the previous display. The only change that is up in the air is when an iMac might get a retina display.
I was only pointing out the other possible changes, but forgot to expand on the new SSD design.
Basically if someone needs a new iMac now, buy it. If not, do you want to wait and see what changes actually make the Haswell iMac.
For me, the biggest reason to wait is the probably upgraded graphics.
