Today, Adobe announced that they were preparing to release the beta version of Photoshop CS3 tommorow, December 15 at Adobe Labs. The beta will be available with Universal Binary support for Macs, along with versions for Windows XP and Vista.

It is expected to be fully released some time this spring.

Packed with new features, Photoshop CS3 beta also includes a pre-release version of a major upgrade to Adobe Bridge, as well as a preview release of the all-new Adobe Device Central. Photoshop customers can use Adobe Device Central to design, preview, and test compelling mobile content, created specifically for smaller screens. This new tool, integrated in the Photoshop CS3 beta, simplifies and accelerates the creation of mobile content through a preview environment and built-in device profiles.

“This is an exciting time for the Mac, and Adobe wanted to ease the move to new Intel-based systems with a preview release of Photoshop CS3,” said John Loiacono, senior vice president of Creative Solutions Business Unit at Adobe. “We didn’t want to leave Windows customers out of the party, so the beta is available to everyone in the creative industry’s most passionate user community — no matter what their platform choice. We still have some surprises in store, but this beta gives customers an early chance to see the power of another great Photoshop release, optimized and tuned to run natively on the latest hardware and operating systems.”
