There were multiple rumors that appeared to have some teeth, so we had hoped for an official announcement.
Instead, we got a flat denial. Two recent rumors supporting the idea that Valve is currently working on Half-Life 3 : a dissected Wheatley speech from an entertaining video at the Spike TV Video Game Awards, and a supposed hint from Valve boss Gabe Newell. But Chet Faliszek was quick to set things right in the Steam forums :
"You are being trolled.
There is no ARG.
Wheatley’s speech was set in Portal 2 fiction – that is all.
There has been no directive from Gabe to leak anything. That is all false.
I just want to say this so there is no confusion. This is the community trolling the community nothing more. While it is nice to see people excited about anything HL, I hate seeing people be trolled like this.
Well, that's disappointing. But at least there's a response now, and we can all stop speculating. …oh wait, that won't stop the speculation, now will it? It could very well be that Valve is simply protecting the secret, or maybe they're not far enough along in the project just yet. Who knows? We just know we want Half-Life 3 at some point.
