CS 3 just around the corner: http://www.thinksecret.com/news/0508adobe.html
There has already been some demos of the CS3 beta running on Intel Macs by Adobe.
I having a feeling Steve Jobs will be all over it at the annual MacWorld keynote next month when he always (until last year at least) loved to demonstrate how the PowerMac (now MacPro) was the fastest computer in the world running PS. A demo, which BTW, always sparked a heated battle between MacWorld and PCWorld as to whether the test was representative.
I agree with Bakes - even though I use Aperture now for RAW conversions and photo handling, Photoshop is one of those apps you really need to have if you're going to do digital photography.
