Valve refuses to confirm anything of this, yet new years have seem to brought some official rumours, that the Half-Life 2 SDK will be released soon. This may be because of the email to HalfLife2.net by Rick Ellis, software engineer of Valve Software, noted that the Half-Life 2 SDK may be released soon. Although the confirmation was quite vague of Rick Ellis, it seems to be quite logical and reasonable that an SDK of Half-Life 2 would be released soon. However, Valve Software is still focused on managing their Security Systems more efficiently so no source code or unfinished alpha or beta techical demonstrations may be hacked, stolen, and leaked by hackers, so it would not seem logical that the SDK of Half-Life 2 be released before the game is actually speculated to ship, supposedly April 2004, well, I really hope so among others, of course!
