Saw this list on a German site (http://www.looki.de/xbox_live_marktp...te_n89977.html
) that claims to have a roadmap to the deals upcoming, including today's Fallout deals, but it's possible the article was written after Fallout was discovered. Nothing listed for tomorrow, so it sounds slightly shady, but a good read nonetheless.
12/22/2011: Fallout contents
24.12.2011: Street Fighter 3 Third Strike Online Edition
25/12/2011: Fruit Ninja Kinect
12/26/2011: Forza Motorsport 4 content (including Season Pass, avatar items)
12/27/2011: Reach Halo content (including Gond, packs, avatar items, etc.)
28/12/2011: Sonic contents
12/29/2011: Red Dead Redemption content
30/12/2011: Gears of War 3 content (including Season Pass Add-ons and avatar items)
31.12.2011: Call of Duty contents
It also seems odd to have a sale on the Gears 3 season pass, and "only" Fruit Ninja on Christmas. Take it with a grain of salt and re-evaluate it on the 24th when that deal is announced. Figured it's something though. Don't shoot the messenger if it's fake.
