Update: Kevin Rose has a new blog post up, with some additional info:

iTunes 8 includes Genius, which makes playlists from songs in your library that go great together. Genius also includes Genius sidebar, which recommends music from the iTunes Store that you don't already have.

With iTunes 8, browse your artists and albums visually with the new Grid view; download your favorite TV shows in HD quality from the iTunes Store; sync your media with iPod nano (4th generation), iPod classic (2nd generation), and iPod touch (2nd generation); and enjoy a stunning new music visualizer.

(Thanks Bad Ash for the update!)

Original post after the break...

Kevin Rose is going to get someone at Apple Jobsbliterated. If all these rumors he's leaking are true, that is. First it was the new iPod Nano (which is looking likely), then the September 9th date for the Let's Rock event (confirmed), and now he's back Twittering additions to his previous iTunes 8 recommendations rumor:

the new iTunes 8.0 visualizations are really trippy - there is one with planet like objects wrapping around each other w/stars/light streams

Certainly not a major new feature by any stretch of the imagination, and we'd call immediate shenanigans if we didn't think there was just the sort of 60s flashback stuff Steve Jobs might be hankering for these days.

We'll see what the 8-ball says but in the meantime, can you digg it?
