The voice actress who provided her voice for the character of GlaDOS in the Portal series hinted at the next Valve title through her twitter account.
Ellen McLain posted the tweet yesterday stating that she was going into the Valve studio to do Portal work as well work on a new game.
"[GlaDOS] is going in Tuesday for a new game and more Portal work,” tweeted Mclain.
She also mentioned that her husband John Lowrie, a Half-Life 2 and Team Fortress 2 voice actor, would be accompanying her.
No word yet from Valve on the matter, but let’s hope the developer is getting their gears in motion for another Half-Life 2 episode or better yet, Half-Life 3.
