I woudn't be worried too much as they announced a 1 billion $ stock buy back program at the same time so they must be expecting huge profit next quarter...
I think the fact that the console business is so seasonnal for Activision probably caused those losses.
There are probably costs linked to the merger and the closing of some of the studios they announced last month too...
Edit : If you look at the press release they had 278 million $ one time costs due to the merger and the closing of non core business ( read those few studios they closed).
