We know 
Looks like my prediction is coming true about EPISODE 3.

Made this time ago, and I didn’t expect the release date for episode 3 to end up being true.
Sigh…
It feels strange to have to complain about a sequel to one of my favourite games, especially when it could actually be very good. Valve could have done so much more with this.
Half life 2: Episode 3 is long overdue!
Episode 1 - June 1, 2006
Episode 2 - October 10, 2007
Episode 3 - 2011, 2012, 2013, 2014?
Valve really need to get a move on. This should have been out in 2008, now I really expect it to be at least the size of Half-Life 2.
I have a lot of respect for Valve and their work, however it has been 3 years since episode 2 and people are getting tired of waiting.
They should have just made Half-Life 3 and had six years of development time like they did between HL and HL2. (Meaning that Half Life 3 would be releasing around now.)
I could rant all day about this however it would get boring…
Oops what?

I demand portals that sets zombies on fire!
Founded in 2004, Leakfree.org became one of the first online communities dedicated to Valve’s Source engine development. It is more famously known for the formation of Black Mesa: Source under the 'Leakfree Modification Team' handle in September 2004.
