All New Black Ops Escalation Map Pack: May 3rd!

The All-new second map pack is coming out for xbox 360  on May 3rd.  It looks like it has 4 all new multiplayer maps called Zoo, Hotel, Convoy, and Stockpile, plus another zombie map called "Call of the Dead"  Seems pretty cool to me.  It will probably be 1200 Microsoft points, or $15.
