The primary source of official information about Forza are the articles on the News page on this site and in the Forza Hub. Special announcements may pop up between regular bylines as in the Forza Week in Review (Fridays). The weekly livestream cadence on the official Mixer channel show off new content. The official Twitter account is also used to alert users of temporary issues and there is also the Forza Support Twitter account which is used to send out updates on critical support-related issues.
Since the News page only goes back a couple months I have created a Official News, Livestreams, and Twitter alerts thread on the forums for a running compilation of past news. You can also see links to older articles in my www.bit.ly/FM7spreadsheets and www.bit.ly/ForzaCalendars at www.ManteoMax.com. See also my Chronology of Forza video playlist on YouTube with over 650 official trailers and interviews going back to 2005.
When posting new info on the forums or asking about something you heard elsewhere, provide a source link for other community members to review. Despite rumors of scanned cars or tracks etc, nothing is official until announced by Turn 10 or playable in the retail game.
