The universal binary still hasn't been released and probably never will because the great people at Autodesk purchased Alias and they've killed development. Any email to them lately gets me forwarded to their knowledge base which is pretty much ignored by them. I guess they wanted to own Maya but could care less about Sketchbook yet they're still trying to capitalize on it by selling it as one of their flagship designer tools.

This is much worse than what Adobe did to the Macromedia products because they've actually improved them a little bit.

I think the only thing that Autodesk did for Sketchbook is replace the Alias logo with their own. A good way to tick someone off is sell them a $200 program and then kill support. Autodesk needs to fix the software or stop selling it altogether.
