@IrrelevantJohn: Don't hold me against it, but I believe the four hours is based off of the playtime count in Origin. So if you decide to stop playing after 2 hours, you still have two hours left.
@IrrelevantJohn: I'm playing tonight, and I know a few others on the list that are.
Also, Burnout Paradise with all the DLC is 3GB, while NFS Hot Pursuit is 8GB. So 5.5 GB seems about right.
For those wondering regarding Turtle Rock's leaving Valve, Doug Lombardi confirmed it at E3 2009. Technically, Left4Dead 2 wasn't developed under Turtle Rock's name.
