The Mac Observer has Live Coverage of Keynote where iTunes 6 is supposed to be announced. Coverage starts at 10am PST (or 11? whatever..., keep an eye on the page).
Update - OK, sites with updates: MacRumors, stuffmag.co.uk and MacNews.de. Short story is new iTunes, new ipods, video ipods, new imac with built in isight, and new apps. Looking foward to Apple.com being updated.
