PF has scored some info on the next HL patch, by way of the latest issue of PCGamer.. Check it out:
Most is TFC only, but I'm sure there are a couple things that cross over (eg VGUI).» The new version (read: patch) has an expectancy by PCGamer (read: not necessarily Valve) to be out in a month. » The new version will be called Team Fortress 1.5 (I assume there will be minor bug fixes for Half-Life as well). » There will be three new levels: Warpath, Epicenter, and Dustbowl (not all CTF, Thank God!) » The new patch will use the same netcode as Team Fortress 2 (this is an update for all of halflife so mods like actionhalflife, counterstrike will have the sleek code too.) » The new patch will also contain a new Internet control system dubbed VGUI. (I have no idea what this is) » "Dustbowl" is a map with a new game mode we've yet to see in TeamFortress Classic. In it, one team must carry their flag into the other teams base within a certain time limit, while the other team defends. -- Sounds a lot like assault with the clock timing each side. » Valve also announced that a new version of Worldcraft would be released, bringing it up to version 3.3. » A new Half-Life software developer kit (HL SDK 2.0) will also be released. Both applications will have a slew of new features and options.
