I'm bit confused.
Could someone summorise for me what comes after AE CS6 and what is the difference? (not in functionality, but usage)
Will there be CS7 update, I'll be able to patch over my CS6 and keep on using it, or do I have to use that cloud thing now? Which (if I get it right) requires internet connection and regular fees?
(standing before desigion wheather to buy plugin elements 3D or wait until its implemented in AE along with lite version of C4D as I've red somewhere)
There is nothing but the cloud these days. Either you keep using your CS6 for the rest of eternity or you will have to sign up to the subscription model.
Answers to many questions about subscribing to Creative Cloud can be found here:
After Effects CS6 is version 11 of the application. The current release is version 11.0.4.
Version 12 of After Effects is branded as After Effects CC. The current release is version 12.2.1.
Version 13 of After Effects is branded as After Effects CC (2014). The current release is version 13.0.0.
All of the above versions are included with a subscription to Creative Cloud. They will install as separate applications, and can all be present and running on the same machine at the same time.
