Half Life 2 Episode 3

It starts getting more and more depressing each year waiting for E3 just to hear any word from Valve about episode 3. I love valve and have bought almost every game they have released but damn all i want is to finish half life 2, four years and still waiting for a conclusion is killing me. After hearing about Valve not showing any products at E3 it wasn't disappointment i was feeling it was a wave of  "damn it, well it better be amazing when it is finished". After playing through Portal 2 and loving every minute of it, i still believe that Valve is the best at what they do and they always put out the very best games. So when Valve finally decides to show episode 3 i expect it to be amazing. Please god i hope im right........
