I think Collider might be right on the E3 content ( above post^). I agree with you on the info lately, but I still feel like they're baiting their hooks and fishing.....just to see who bites and how hard. 
True. Quite a lot of the answers I've seen seem to be a "Yes-No-Maybe" answer, where although the answer is there, the question is still left unanswered, or just opens up another question.
Yea. But I have a feeling that they'll just the repeat the older news since E3 is so prolific. They don't really need to do anything special or new.
It would be cool to see them discuss/show Tali's new character design (as they've said they've updated the looks for every major character/squad mate).
True enough. At this point it'll be good just to see some stuff like the weapons, combat, and other such stuff.
