Strikeforce still exist, they're running as normal. Scott Coker is in charge, all the fighters are still Strikeforce/Showtime fighters, and they're still entirely seperate entities, the UFC just owns the rights. It's very, very good for MMA. Strikeforce were a mess, and they now have the experience, the business smarts and the promotion from ZUFFA. This is a fantastic deal for Mixed Martial Arts.
