Maybe that event is another clue to the next virtual villagers?
Which event are you referring to? The barrel of babies event has been around for a couple of VV games. The one that mentions the golden child could be a clue to the next VV game. In the guides section, the event that sends a villager or two from another village your way has been around since VV2, but I think this is the first one that actually directly references the first village or even the golden child him/herself.
It's really all speculation right now and LDW isn't giving any clues.
