Money hats? It makes more sense that they're gonna focus on their own console instead of dosing out games to other consoles which never move large amounts of their games anyway. Besides, Valve were never big fans of Sony and the PS3. If they choose to support MS, its because it makes sense to do so, Left 4 Dead games have sold near 7 million on the 360
Simple fact is; Valve don't need the PS4, or the next xbox.
