Facebook-MySpace Announcement Thursday?

Updates at the bottom of the post…

SAI just posted that Facebook and MySpace are holding a special announcement Thursday at noon PST:

SAI is stumped as what this could be about, but … we can certainly speculate too.

• MySpace and Facebook working on a new bands-music channel?
• Myspace throwing in the towel to Facebook (unlikely as News Corp would have had to say something about that)
• More sharing between MySpace and Facebook?
• ???

We’ll update this post as more info comes in … but speculate and discuss in the comments!

Update: From All Things D and Inside Facebook it looks like the announcement will be MySpace using Facebook Connect to power logins. Man, thinking about MyFaceMusic was much more interesting…
