If anything I'm noticing a pattern here. They started with 6, 4, 5 and now 0. This was also the same pattern with the special radio messages. So does that mean X is next?

One more thing, another pattern is the air/ground type. It started with Moby Dick (air), Stonehenge (ground), SOLG (air) and now Excalibur (ground).

In the end, I speculate that Gleipnir or a Fenrir raid is next.
