I am surprised to hear you say that press ignored it, because it was rather extensively covered. Also, FBI this time around are not at all direct, they won't even state that they are investigating Hillary again. Both of these facts combined makes me think it is all hat.
The original email server story was months ago extensively covered in the US most likely outside not realy, main difference is that Trump has always seen as a joke with Hillary the president in waiting, now they are starting to worry that Trump is going to win.
The BBC has had this as their main story all weekend
