A possibilty for the next WCry-kind of worm

During the past days the WCry worm has caused more damage than probably any previous internet meltdown. This one was used for ransomware. What about this one: An organised crime unit develops something similar to WCry. But in addition to using it as a ransomware, pre-knowledge about what will happen is sold to other criminal elements, alerting them about when and what will happen. Thus, the general chaos can be used to conduct other criminal activities, terror acts or espionage.
That would be a kind of nightmare scenario.
