Yes, because my only expectation is that I enjoy the game as much as I have the entire series. It's not like I expect the game to age like wine the longer it is in developer, wishing it to meet some vague, indescribable standard of enjoyment based on how long it's in development. I don't expect it to be more revolutionary or more fun as time goes by.
My expectations now are almost identical to my expectations post-Episode 2. I want a Half-Life game that meets the same standard of quality and enjoyment I've derived from the series so far. Each episode has left me in awe at the set pieces, engaged in the encounters, lost in the game world, enthralled by the story, and ascended into a world of pure gaming bliss. That's what I want, as it's what I've gotten from the series.
The only shaped expectation I have is the size of the game. I'm expecting Episode 3 to essentially be Half-Life 3 in scope, and I'd probably be a bit disappointed if it turned out Episode 3 was indeed just one episode in length. If it still met the above standards then I doubt I'd care in the end, because I got the Half-Life I wanted, but I do want Valve to throw themselves into a full length product with this game.
