Errr....Merchants in prontera buying orange for a nice price sinse this topic was open......I will be very sad if Duff's need orange in the quest......(becosue it means someone of staff have left information about the duff's quest)
Players are most likely expecting the same as last year's event which used oranges, no "staff leak" required for that.
Staff have not confirmed if it is the exact same requirements this year. We will not know until the event is live or if they confirm or deny any changes.
I lol'd that was funny enough that I actually signed in to post this.
