As I mentioned last night Rational just announced its "Atlantic" wave of products. I didn't mention any specific features because I didn't think Rational had gotten that far along. Well it turns out I was wrong.
If you go to this page it lists all of the Atlantic products including the ones I'm looking forward to, Rational Application Developer (RAD, successor to WSAD) and Rational Software Architect (RSA).
So anyhow, there is a datasheet for each product that enumerates features and even has screen shots of the much-improved UML graphics engine and user interface I mentioned yesterday. The links are below. You'll need Adobe Acrobat Reader for each.
