No, it does not look any different. In fact, a lot of its code is from an earlier version of the 2.0 tree, back when there were still certain features not yet implemented, and certain bugs not fixed. The main advantages in the 3.0 portions of the code tree are related to the new 3.0 audio engine, the same one that's used on the Karma. Primarily what you get with 3.0 is: crossfade, pitch bend, OGG, and FLAC. Otherwise there are no new improvements in the user interface and in fact there are some features missing and some old bugs cropping up again.
