Various stuff unrelated to HL3
You know what Valve and Gabe like more than fun? Money. Half-Life titles make them a bundle, both directly through game sales and providing value/attachment to Steam. Valve working on other titles or going into other markets (most of which are actually properties they purchased along with the employees) has nothing to do with episode 3/HL3. You've offered a lot of sniped quotes and text but nothing of substance that points to HL3 not showing up.
Wake me up when Gabe literally says HL3 is not in development, you're so willing to take him at his word after all
