There's a new arg for TF2. Probably on the End of the Line/Lecture Valley updates.
There's http://forums.steampowered.com/forums/s ... ?t=3209522

In short, new posters were added to any maps with billboards, and a lot of maps got a whole lot of other posters too.
Decoded in 3 different ways, the numbers on the billboards read BE SURE TO DRINK YOUR JARUTE [sic]; TREASURE YOUR DRINK, YOU RUT; and I DRY SUTURE YOUR ROKER TUNA.
In addition, at the conclusion of the last arg, the TF2 team had a sentence saying how they might send TF2 to space next time. Looking at the engie's pictures, he has a whole lot of space-related blueprints (engine, rocket, etc.). Poopy Joe is also hidden under the Medic's pic.
It should be noted that this is probably a red herring since the scout is holding a literal red herring.
(Also, it should be noted that jarute could also be jar-bat-e)
