Ok, guys, put down the torches and pitchforks, and do the following:
1. Head to www.xbox.com/re5
2. Hit Shift+5
3. Click the banner that changes from Resident Evil to Resident Live
3. The word 'badlands' now appears in the upper banner. Click it before it disappears.
Shift+5 is a code that actually unlocks the page, as opposed to just being a candle you can move around. There are some viral videos, new screenshots, and a Q&A.
No mention of any DLC at all.
Edit: Ok, that procedure might be incorrect--I'm having trouble duplicating how I unlocked the page. But it's definitely there.
Edit 2: Fixed it--click 'badlands'.
