Well, this seems to be the most versatile version of intro so far. (If i only could get the darn think to work properly!)
In previous versions you could use up to 8 internal instruments (drum rack, impulse and simpler only, but you can buy the others in the store i think.), 12 internal effects (vocoder and looper were missing among others, but i missed these the most), 4 vst instruments and 12 vst effects. With no chance to use group tracks nor racks. And you could use unlimited audio and midi tracks.
Now with intro 9 you have unlimited external and internal effects, however you're limited to 16 tracks (regardless if they're midi or audio tracks). You have racks and grup tracks enabled, and you have the looper now, but in exchange you loose eq8.
Since i've always used live as a composition tool and then move on to logic pro and my hardware synths for the production stage, Intro is more than enough for me. I recommend this way of working, as limitations tend to make you more creative.
Cheers mate. I hope i've answered your question.
