The pros aren't gonna be running iMacs... sure it shows that the iMac can run it, but that's not how the pros are going to run it. If you are a pro running shake you will have a G5 (or a cluster of G5s) Powermac(s) that you are running it on. Intel has also bumped the release date forward for it's next generation processors. I can see all of this stuff being released at WWDC and apple can watch it's competition "shake" in it's boots.
