launch of Adobe CS5 suites has begun (via #csbuzz). You can register for the event and look at sneak peeks at http://cs5launch.adobe.com.
Update: See also the very cool Sneak peek video of Content-Aware Fill in Photoshop via John Nack. Older sneak peeks were already noted on AEP along with other more academic technology explorations.
Update: Todd Kopriva reminds us that if "you're thinking about making the move from After Effects CS3 to After Effects CS5, don't forget about this other great stuff that comes along" from CS4.
