This is a really good question.
I voted "no", because I'm enjoying getting the weekly updates and I am totally hyped/stoked for the game, but I can understand the other POV as well.
I noticed a drop-off in the general level of interest after the release target date announcement as I think most people were expecting a 2010 release date. With the game still a year (or more) away, I think it might deter a lot of fans from remaining avidly interested at this point.
That being said, I think the marketing team at BioWare/LA have done an amazing job so far. The hype for this game is almost palpable still, despite the delayed release date, and I think it has as much to do with the marketing techniques as it does the Star Wars franchise tag.
