I can see the gaming apocalypse now, as portrayed by a zombie film:
The Wii was the bit character who died within almost immediately to show how dire the zombie threat was.
Xbox was the burly guy (played by a professional wrestler) who got killed by zombies when it seemed like the group was safe.
PS3 is the untrustworthy guy who'll probably betray the group late in the film, and possibly was the cause of Xbox getting killed.
PC is the main male lead who was bitten by Wii shortly after his infection, but endures for the sake of his love, Steam. Whether he succumbs to the virus or takes his own life, we'll have to see...
