King in Black #5 (of 5) has been delayed two weeks, with a revised on-sale date of April 7.
Apparently as a result, the next two issues of Venom are also pushed back - Venom #34, is shifting back to match King in Black's April 7 release. With that, the next issue - Venom #35 (a.k.a. Venom #200) has also been delayed, back to May 5.
King in Black: Planet of the Symbiotes #3 (of 3) has been rescheduled to April 7, away from its original March 10 release date.
