Will Valve announce Left4Dead for PS3 at the VGAs next month? Is this the special PS3 exclusive news Sony has been teasing?
These are just two questions set in motion by eagle-eye viewers of the VGA teaser ad that outed Bioware's new game earlier this week.
20 seconds in, the video flashes up the image shown here. A faux public health announcement, it screams: 'Infected? Report it!'
So, it's definitely zombie-related. But LFD? We'll have to wait for the VGAs to find out. The awards will take place at 8pm Eastern Time on Saturday, December 11 (1am on Sunday, December 12, UK time).
The video also teases a new American Football game. But that's probably of less interest to you.
