Adobe Creative Suite 4 (CS4) is the planned successor to Adobe Creative Suite 3. It is currently being developed by Adobe Systems. Public betas of some applications (Dreamweaver, Fireworks and Soundbooth) were released on May 27, 2008. Currently, little is known about the development of CS4. New versions of Photoshop and Flash are known to be in development, and have been released to select beta testers. Other applications from previous versions of Adobe Creative Suite 3 are also assumed to be in development. CS4 will be available as both 32-bit and 64-bit applications for Windows, but only 32-bit for OS X. There is currently no public release date or pricing information for Adobe CS4, although there is speculation of a release date in late 2008 or early 2009. So far, only a limited number of applications from previous versions of Creative Suite have been confirmed to be in development. These are: Adobe Dreamweaver - codenamed "Stiletto" Adobe Fireworks - codenamed "Ignite" Adobe Flash - codenamed "Diesel" Adobe Flash Player - codenamed "Astro" (a new version of Flash Player may be released separately from CS4) Adobe Photoshop - codenamed "Stonehenge" Adobe Soundbooth It is assumed that other popular applications from previous versions of Creative Suite, including Bridge, Illustrator, and Premiere will be updated and included with CS4. Some new applications, including Thermo, may also be included. Additionally, it is possible that existing applications will be removed or merged together, given the several overlaps in Adobe's product line since acquiring Macromedia, and comparable feature consolidation from CS3.
