I think that BioWare is finally able to pull together some similitude of WTF they're doing, by now at least.
What they're prolly gonna show is a trailer, with some more hints... Then we're gonna go black again (at least as far as info) until some time well into next year.
EDIT : The only question now is, how big will those hints be?
<<<<<<<<<<()>>>>>>>>>>
Apparently these "hints" will be of the amorpheus kind. Bio will not tie themselves into a specific direction unless it's already written in stone.
For example:
Bio may introduce/confirm another MW race but won't mention anything about their purpose (ie: as a NPC or as a squad member or part of their own colony ship(s)).
For example:
More conceptual art which will look different in the game.
For example:
Bio will mention you can skip cinematics but fail to mention some are unskippable or that's only the intro cinematic.
For example:
Bio already mentioned that they are serious about character equality. What does that mean?
For example:
Bio can say exploring new worlds with the Mako is Awesome... but fail to define awesome.
I think you get the picture. The thing is, in my view, it's too early for Bio to announce concrete game elements.
