Z2Live tends to be very quiet about their long-term plans. They usually tell us nothing about what's coming up until it appears in the patch notes for a new update, and even the patch notes are sometimes unreliable or misleading. As far as I know, they have said nothing one way or the other about whether or not there will be another Infected event in the future.

If there is, it will most likely be some time around Halloween, like the first one.
