Somebody who runs a SWTOR fansite received an email from Bioware with links to Seeking Henna and the Woods-Watson Institute.
They'll also apparently be at SDCC handing out Woods-Watson flyers.
Also, both those websites were registered by EA around the same time as the teaser website you've-been-chosen.com, or whatever it was.
A cipher in the trailer or email also refers to Henna.
(One more thing: someone is apparently posting clues in the Reddit puzzle thread):
"If you’ve stumbled upon this subreddit by happenchance and haven’t read my blog, please check it out here. If you have read the blog, carry on!
I finally received Henna’s incident report from a… friend. Let’s just leave it at that. There wasn’t much new information. Seriously, what’s the point of writing a report if half of it is just going to be redacted? Thankfully, there was at least one thing that stood out to me: The Woods-Watson Institute.
Henna was home schooled. Why was she spending so much time on this school’s site? And why had she never mentioned it to me? I went to their website, but things just got weirder. There’s no listed address, no information about their admissions process, and it looks like they’re using stock imagery for the campus.
I’m going to be in San Diego this weekend, handing out flyers to see if anyone knows something about this so-called school. Maybe this is just another thing I didn’t know about Henna, but I think it’s something more. It might be the only lead I have."
