Sure, but the number of people actually paying attention to Mass Effect at this point is a tiny proportion of the people who will end up buying it. There'll be literally hundreds of thousands or millions of players who only hear about the game in the weeks before it comes out, or even after it comes out through word of mouth.
The number of people obsessively following information about it on a forum like this one is even tinier. The marketing is not meant for us. People may be suffering "hype fatigue", and that's not necessarily a fun thing to go through, but EA isn't aiming to reach people they already know are paying attention.
I'm holding on to my hype train until I see some game play. Hell, I haven't even started boarding my hype train just yet. I'm sure that it will be good, if even for the story. There are two main things that I really worry about with ME games -- story and mechanics. This is the one reason why I didn't like ME1, and some would say that I still don't -- that I just tolerate it, for so long. The story kicked ass. The mechanics in it, whew.
The story will be kick ass, even if they end up killing everyone and I die at the end. I have that much faith in BioWare's writing team. Mechanics - not so much, but that's only because I have to fight them (if I don't like them) every inch of the way. If I do like them, like in ME3, then all the better.
The main reason that I haven't started my hype train yet, is I've become hype fatigued before and it's no fun. You end up feeling meh about a game that everyone else thinks is super cool. And you can't figure out why.
