Adobe Systems released beta versions of three key applications from its upcoming Creative Suite 4 package of graphic, Web and multimedia software on Tuesday. Preview versions of Dreamweaver, Fireworks and Southbound are available for download.

Adobe did not say when beta versions of Photoshop and Illustrator may be available. David Burkett, vice president of product management for Creative Suite, suggested Photoshop and Illustrator will not be released as beta previews like the other three applications. “Dreamweaver, Fireworks and Soundbooth are the major applications we’re unveiling as public betas before the next release of Creative Suite,” he said.

Current customers of CS3 can use the beta software until the final CS4 package ships. New users will only have 48 hours to try out the new programs. The final version of CS4 is expected in the last quarter of 2008 or the first quarter of 2009.
