Adobe is officially launching Adobe Creative Suite 3 on Tuesday in New York, and CS 3 will ship later this spring. However the bundles seem to have changed since CS 2, with a new range of applications.
From what I have read there will be four categories. Design, Web, Production Premium and Master Collection. I can also mention that Photoshop is split into a regular and an Extended version.

I have had a great deal of problems with amongst others inDesigns compatability with older versions than CS2. Since I will not be able to afford CS3 for a while, I do hope they have sorted this out.
More info should follow after Adobe’s official launch.
