If the updated hardware requirements can only mean updated Source engine visuals, physics and effects, I'm all for it.
The minimum standards can't stay static forever if there's to be any progress in the tech department of PC game development.
If anything, this may end up signaling a wider gap between current PC/360 development, not to say that there would be anything wrong with a port of LFD that looked as good as Half Life 2 Episode 2 on the 360.
