Waiting patiently for over four years is a daunting task, especially when E3 comes and goes without any beat of a Half-Life pulse, time and time again. Valve had stated that information was scheduled to be released towards the end of 2008, and we believe that if they have chosen, for whatever reason, to withhold this information, fans should at least be acknowledged in some way, regardless of developmental plans for the next Half-Life project. The entire trilogy of episodes was supposed to be completed and released by 2007, and if Valve have decided to do other things for the time being, that is fine; all that we ask for is a basic response on the matter, and to let fans know whether or not the current story arc is scheduled to conclude at another point in time.
It's a reasonable request in my opinion. I'd love to hear something from Valve, particularly around engine and SDK updates, seeing as this sites existence pretty much relies on interest in Source as a development platform.
