On the Italian version of the trailer announcement newswire, it says "the first days of December" instead of "early December" on the original one.
Could be just an interpretation issue or a mistranslation, but the Italian version of the "Message from Rockstar Games" trailer announcement, has doesn't have "early December," and instead has "primi giorni di Dicembre" that translate in "first days of December." According to some Italian user, in italy the first days of December usually means anywhere within December 3rd or at maximum December 5th. Other languages of the newswire say "early December" and it seems like Italian one is the only page that has a specific term. Native Italians or people from or live in Italy are free to chime in and correct me!
