Valve attending (only in business area)


Valve also powers a "wave" event:
You can go wild on the gamescom wave powered by valve. It is in the outdoor area, but don't worry, you won't even get wet. A rotating carpet gives you the feeling of truly surfing a wave. The gamescom wave powered by valve is right next to the beach and extends the beach area with another highlight. Grab yourself a board and surf the gamescom wave powered by valve.
Take-Two attending

Valve will probably release some "Steam for PS4" thing as well, parallel to all the work they did around Portal 2's release.

Maybe we'll see a "[insert color] Box" SKU for next-gen with the Portals and Half-Lifes. I'd be surprised if they aren't interested in porting over TF2 or DOTA2 either.
