"They're not doing ongoing development on The Orange Box for the PS3," said Valve co-founder Gabe Newell to 1UP. Valve produced its bundle The Orange Box, containing the team-based shooter, in-house for the PC and Xbox 360, but publisher Electronic Arts had its UK unit handle the PlayStation 3 port.

"We don't have PlayStation developers," added Valve marketing director Doug Lombardi.

The PC version of Team Fortress 2 has received a bevy of content, including maps, game modes, achievements, and weapons--and all of it has been free. That content has yet to be released for the Xbox 360, but it will arrive as paid downloadable content because Microsoft said so.
