Ah, Yahtzee. How many things have you just said to reaffirm what I've thought for years? Everything about cynicism/pessimism and everything about the CGI trailers, both spot on with what I've always thought.
I really do wish we would get more original games, though. Wheres Tim Schafer when you need him? Biggest E3 disappointment was that Brütal Legend did not show up. Schafer seems to be the only long time game designer that hasn't either given up all hope or fallen into lame sequeltopia.
I've given up hope, though, that any of the other original game designers, if there are any, will never show up at E3 since it appears that if it isn't already an established game series or by one of the big boys, then it's not worth showing.
