If you think you know all about CS2, think again.. CS3 Coming out

Photoshop CS2 Coming out…

Adobe is exploring offering two versions of Photoshop CS3, a Standard version and a Premium version. According to one plan under consideration, some principle new features, such as Camera Raw 4, would be available to both versions, while other functionality, such as Vanishing Point 2, would be available with more advanced options in the Premium version. Still other features, such as rotoscoping that was introduced in CS2, would be moved exclusively to the Premium package.
