They're not releasing HL3 until it has something revolutionary in it... You should be cheering them on in their VR and other peripheral pursuits if you want to see HL3 sooner.

I don't think those 2 things have anything to do with each other. Remember, valve employees work on whatever they want to, whenever they want to. They have a flat (as in no) management structure. It usually ends up being what they find interesting and/or fun, and this is interesting to the guy, so he's working on that.
