I only just purchased a CS 5.5 Design Premium (full license, not subscription) lincense 4 days ago, without knowing anything about Creative Cloud.
Now that Creative Cloud is announced, I realized I should have waited a few more days. Creative Cloud is much more exciting and suite my work a lot better.
Do you think there's a chance that Adobe will let me cancel my Design Premium licence and opt for the creative cloud instead?
You should be able to upgrade without having to cancel your curent subscription plus at a discounted rate. Do go through the complete details mentioned on
https://creativecloud-specialoffer.adobe.com/special-offer/?loc=en_US including " full promotional terms " mentioned at the bottom of the page.
The Creative Cloud subscription as of now is only available in Australia and New Zealand in the Asia Pacifc region. Stay tuned to the Adobe Website for more details on when this will be made available in Hong Kong.
