Welcome.
As to the learning curve for CC3, I have heard it is steep, but I just don't see it. Not to sound facetious or anything, but I have a harder time trying to grasp the concepts of photoshop
If you pick up CC3, my biggest word of advice is this. Follow the Tutorials that come with it, (or locate the tutorials for CC2, only difference between the two is the look of the map), and you should do fine.
