Yep, SKY have officially announced that it has acquired the rights to the fourth season of Angel, though when it'll be broadcast (January 2003 would be my guess) hasn't been mentioned.
Oh, and if you're a Highlander fan (and i know they exist here ).. the sixth and final season will be shown from about September 16th weekdays at 1.00am..(and considering there were only 13 episodes made, it'll be done and dusted in just over two weeks).
