BioWare's line for the last couple of years has been, "We will talk about it when it's ready." According to Reid, the mantra still holds true, but the explanation is a bit deeper when considering what it actually takes to be "ready." Presentation is the first on his list, as Reid explains in a post, "While some of you might say 'But I don't care! I'm sure it'll be good in the final game! I can totally forgive you this time!' I'm afraid we don't get that latitude with, oooh, pretty much 90% of the rest of the world." Another reason is some systems that are ready depend on other systems that aren't ready. And lastly, there are public relations and marketing considerations.
In another post, Reid addressed other specific community concerns, such as EU testing and, as one community member put it, "We in the EU do feel like second rate citizen here sometimes." Other concerns like the low amount of developer posts on the forums, in general, and the community's influence on the final game are engaged as well.
