If you follow the link in that thread to the wiki page, there is also a link to the official website with all the info (even though it's pretty much a copy-paste from the Fatal Furies event).

TLDR;

Terrorcons are the bosses (and the cards you'll be able to get as rewards once the event is over)

episode cards = divebomb and razorclaw (as in, new versions that will have X3 and X5 atk bonus)

decepticon R4s get X2 atk for the event (so if you got any Flamewars or Slipstream during this event, you'll be happy : )

The event should start on Wednesday, making it the shortest gap in-between two events, so far!
