Today we learned that the trademark for Half-Life 3 was registered by Valve, and now we get a further piece of confirmation, thanks to hawk-eyed NeoGAF user Ekim.

Valve Software's bug tracker site now includes a group for "Half-Life 3" and a second newly created group named "Half-Life 3 Core", basically confirming that the game is indeed in development. You don't look for bugs in a game you aren't developing, after all.

The site also indicates that 46 developers are involved with the project. Mind you, that doesn't mean that the full team counts 46 people, but that is the number of devs involved the debugging process.

Below you can see a screencap of the relevant page (email addresses have been blurred to protect the mailboxes of innocent developers and QA testers), just in case Valve decides to hide the groups from our curious eyes.

It's happening (unless they're trolling us)!

Update: apparently the bug tracker site is now unavailable again. Valve may have pulled the plug in a hurry in order to hide the smoking gun. Well...too late for that, Gabe.
