Looks like inMusic (the company that owns Denon, Marantz, Alesis, M-Audio, Numark, etc) just bought Rane, likely for their popular DJ products. I hope they preserve the pro audio division of Rane, they make some really cool and useful products.
I think Rane still has a strong foothold in the dj mixer game here in the U.S. That being said Pioneer Im sure is dominating.
I'm going to start downloading the Rane notes for safe keeping.
