I think it's safe to file this under vaporware in the meantime. It's not like HL1 is THAT great of a game by modern standards. Sure it was great by 1998 standards, but 14 years have passed with modern games offering a much more immersive experience along with much better gameplay and AI. Nostalgia is nice, but the hard truth at the end of the day wins out. So recreating an experience that was severely limited by 1998's level of technology is just plain stupid to me. If Valve would make HL1 today it would be nothing like the original.
