Are you aware of the work it takes to write a new engine from scratch? A hell of a lot. They are working on the "Valve Engine" for HL2, TF2 and CS2. It takes a lot, not to mention the story/script writing, game design, textures, themes et cetera.....

Be patient, they'll let us know when they are ready, I'm not going anywhere and neither are you. Play Natural Selection, that's good stuff, play other games, it doesn't matter because before you know it we'll have a crapload of new screenshots for their new project(s).

I for one am excited. People like to dog Valve and talk about how they can't code, using the HL engine as an example. Well that's a bad example, hacking an engine up can make things run pretty bad for anyone. Stats on their new renderer should be interesting. I'm excited to see what they'll have in store to compete with iD, Epic and Lithtech.
