Actually I don't know why I am so excited to announce this since I am not entirely sure there was anything I was missing from iTunes 9!
And here's a hint... it took like maybe 20 minutes or so to do the whole download (without MobileMe) and then when you start iTunes, it goes through your whole music library and updates it. I only have about 800 songs and this took forever!
And of course, you will have to reboot your computer.
Well now at least I am current... for now... until 4.? gets released in November.
