It could simply be of course that they were waiting for more to be cemented before engaging. It won't be as if they've ignored all the feedback and comments since release of EA, but other than the "...from Hell", they've perhaps simply felt it was too early in the process (rightly or wrongly).
For example they might have toyed with drag and select vs chain for movement, but have decided to stick with Chain due to console constraints (just an example) and rather than update us constantly and get hopes up, they wanted more systems to be firm before having that level of engagement.
Not saying any of that is true, just trying to provide a counter argument.
