Michael Arrington at TechCrunch let a cat out of MySpace’s bag a little early, revealing that the company would announce the departure of co-president Jason Hirschhorn tomorrow. A representative for MySpace just sent us the following statement from News Corp. Chief Digital Officer Jon Miller on the matter:

We fully respect Jason’s decision to leave and his personal desire to return to New York.  As many people know, Jason is like family to me, and as expected, he’s done everything we asked of him and more.  We’re incredibly grateful for the passion and enthusiasm he brought to the company.  And as I know Jason agrees, Mike Jones has done an outstanding job leading MySpace into its next evolution and is the right person to take the reins.  There are no plans to bring in additional management.

There you have it. Perhaps more details will still be officially revealed tomorrow. But at least it’s been confirmed.
