The article mentions significant improvements in Toast 6 over 5, but for my needs I doubt I would use some of the "new features" very much. Improved support for CD burners (I use the combo drive in my powerbook) and more artwork to make covers with I don't think I would use.
Hmm .. on the positive side, it does look like improved audio, video, and photo CD features will be a big plus. The Motion Pictures feature reminds me of the Ken Burns effect in iMovie though 🙄
I'll have to see, I don't see an immediate need to jump out and upgrade as soon as this is released, but further reviews and more feature descriptions may help my decision.
