I subscribed to PS CS5 few weeks ago, can I upgrade to CS6? Will Adobe send any upgrade notes?
Yes you will be able to upgrade to Photoshop CS6. For additional details please review Upgrade policy after product announcement - http://helpx.adobe.com/x-productkb/policy-pricing/upgrade-policy-produ ct-announcement.html.
You should receive an e-mail or you can go to your order page and download Photoshop CS6 once it is released. It is not available at the moment though. You can certainly try the Photoshop CS6 beta though while you wait.
