Adobe CS4 announcement expected Sept. 23

Just when you thought you just bought (or just finished paying for) Adobe Creative Suite 3, get ready to take out another mortgage for Adobe CS4, which will be publicly unveiled on September 23. AppleInsider conjectures the software will drop in October.

Adobe will be delivering several webcasts that day to showcase the new software to the public. You can register here to participate in the webcasts.

Improvements to Photoshop and Flash are expected to headline the event. Adobe did not release any details about how the software will be bundled, nor any pricing information. Full versions of Adobe CS3 can cost as much as $2,500 for new users, and $160 for those who want to upgrade.

Adobe released preview editions of Dreamweaver, Fireworks and Soundbooth in late May.
