So I’m a couple days late or so but I’m sure you’ve heard the news about CS4. Seems there are some solid features added and some great integration with flash and PS which will help a lot of people. Check out the Adobe product page for specifics.
Here are blogs to check as well.
Admittedly I haven’t reached the depths of every new CS3 feature but Adobe maintains the core functions of the application so that even our very first tutorial can be followed with the newer versions. One thing I heard is that CS4 should work better with larger projects and I hope that is true.
If you look at the big picture, After Effects 6.5 has enough capability to create things that would stop time and newer versions regard this as well. After effects is a compositing application and it is up to us to build amazing things. No new feature is going to do that for us…
Of course all of our products work with future versions of After Effects if you plan on upgrading now or in the future.
