Actually, I did not know that.
Still, they said they were going to do an Episode 3 right?
And they said that before they announced Portal 2 right?
*wink wink*
Not wishing to turn this into a HL2/3 thread, but:
There was an interview with Gabe Newell on gametrailers a few months ago, and he was asked if Episode 3 was so big it had turned into HL 3 - he laughed and refused to comment. He also said that they were still working on HL in response to a question asking if they'd abandoned it - 'of course not'.
Mind you, in the same interview he said Valve weren't doing anything with the PS3 - 'not in any serious way, no'.
And didn't he say more recently that he thinks HL needs to be scarier?
