Half-Life 3 t-shirt sighting aside, more convincing evidence has surfaced suggesting the title is in development — and fairly far along at that. Official Xbox Magazine reports that a US-based voice actor recently recorded lines for Half-Life Episode 3.

While it’s been rumored that Valve had planned to drop the episodic approach for awhile now, it’s possible that Valve still refers to it as Episode 3 when dealing with contract work. If voice-overs are being recorded, it would suggest the title is well into development — and finer details like the setting and underlying plot already finalized.

More concrete info would be nice, but when it comes to Half-Life 3, we’ll take what we can get.
