It's my understanding that the new look also reflects a new owner and a different approach--not so "Saxon-y." Some folks are quite annoyed about this. I'm not sure what I'll do--my daughter is in 76 and I'm a fan, and I'm wondering if I'm going to like the new editions as much.

If you would take a look at the January 2010 news article at Using Saxon Math I believe your question about which editions of John Saxon's books are still valid - and will be for several decades - will be answered.
If you still have questions you can reach me at my office at (580) 234-0064 (CST) during normal office hours.
