The wait is nearly over! We can now confirm that Adobe Creative Suite 3 will be announced March 27, 2007. The company is celebrating the launch at an event in New York City that will be webcast live at 3:30pm ET. During the webcast, Adobe will reveal the features and suite configurations that make this the largest software release in Adobe’s 25 year history.
Just a little bit longer before we find out all the new features of CS3, although the biggest ones are probably already known. The blog post mentions that even though the announcement will be made later this month, the actual release won’t be until "later" in the spring.
