For the people who think that releasing closer to the holidays (for a game like this) is better marketing sense ...
HOW DOES THAT MAKE 'ANY' SENSE?
Release now, and the product will still be available for the holidays!!
Your logic is damn, silly
gah, lol
Who said that there will be a new engine for HL3?
I think the implication of the highly scalable/modular nature of Source's design is that it will be changed and will evolve over time
Meaning, HL3 will most likely use 'Source' also, but by then, many advancements and enhancements will be...
I actually admire the platform.
However, I've only had one problem with it, it crashes during HL singleplayer
For example, I can't pick up a battery without the game sending me to my desktop with an error message in my face.
Weird, but oh well, maybe it's my configuration or something...
