The good news:

MySpace.com is upgrading their Flash based music and video players to Flash 9 *NOW*.

The upgrade is "automatic" when you log in to your MySpace account.

This means that F9 Player adoption rates could be much faster than it was with previous versions. (Or at least it will be a quick steep adoption curve for certain demographics).

(The Bad news:
Right now their upgrade just isn't working. (As of July 20, 2006))
