Well being that most high end audio programs are pretty mature now, I'm thinking there isn't much to improve other than workflow.

There's quite a few big things they've done though. Sample accurate editing ala pro-tools in the arrange window.

Comp swiping - that's huge! Major time saver there.
Multitrack record editing that is a lot easier, another time saver.

The delay designer plug is slick. I've been looking for something like that for a while.

A customizable interface and the new general layout looks great to me.

From my grapevine I've heard that it's a major step up except for one thing. Apparently there's no more "bus" objects. The way Logic 8 deals with busses is apparently different and because of that difference it has issues with importing songs done in older versions of Logic. Thus it means keeping a version of Logic 7 around when you want to make sure you've got it right in terms of your old mix.

You generally don't want to upgrade in the middle of a project, but since I'm in between things it's gonna be easy for me to make the switch. And I'll get to import a project to see how that problem rears itself.

I'll be staying up late I'm sure. :-)
