Welcome to Adobe Forum,
Every aspect has two sides of coin, graduating to CC subdcription has more postive effects for the future technological growth.
A glimpse of it is documented in http://www.adobe.com/products/creativecloud/faq.html
But soon it will not be supported nor upgraded.
Any further upgrades will only be available through the Cloud.
That is true... and that is a choice that only you may make for you
