It would be an understatement to say that there's been a lot of interest expressed about the forthcoming release of the full Source SDK. Well, the time draws near! I'm not going to mention a specific day, but certainly the word "soon" is appropriate here.The upcoming release will include Half-Life 2 mapping support and additional sample maps, support for cubemaps, and the mod source code.Just a little while longer and then we can truly begin with the modding and mapping.
