This is what Adobe said today:
We’re very excited about the upcoming release of Adobe® Creative Suite® 6 software and Adobe Creative Cloud. CS6 will be a major new release of our creative desktop tools, with huge improvements for every type of creative professional. Adobe Creative Cloud will be our most comprehensive creative solution ever, giving members access to all of the CS6 desktop software plus additional services, new tools, Adobe Touch Apps, and rich community features. In addition, Creative Cloud members will receive continuous upgrades and updates to all products and services as part of their membership. With these great new releases coming in the first half of 2012, we want to make sure our customers have plenty of time to determine which offering is best for them. Therefore, we’re pleased to announce that we will offer special introductory upgrade pricing on Creative Suite 6 to customers who own CS3 or CS4. This offer will be available from the time CS6 is released until December 31, 2012. More details on this offer, as well as any introductory offers for existing customers to move to Creative Cloud membership, will be announced when CS6 and Creative Cloud are released later this year.
Details on upgrade pricing are available from Adobe’s Web site.
