I'd also say "anticipation" is the wrong word for the expectation behind the desire for information on MEA... 
Well for me, its a mix of anticipation and skepticism with a generous sprinkling of optimism on top. I'm sure Andromeda is going to kick ass and I will love it. But after it is released, in retrospect would it have been even more awesome otherwise? We will never know. And if it has major, major storyline issues after release, we will probably look back and wonder if all of this was the cause.
It's also worth noting that when we all predicted that the story would move to Andromeda long before the leak and the official announcement, a ton of people here were very vocal saying it was a horrible idea. I have always supported the move, but if the story ends up majorly sucking, then it could be a big problem for continuance of the series. People would point to the move to Andromeda and the desire to escape the endings of ME3 as the thing that damaged Mass Effect. Conversely, if Bioware rocks this, people will praise the choice. Gamers are fickle. I am very much hoping for the latter, but all of this isn't exactly boosting my confidence lately.
