I had found an article previously that was dated June or July of 2014 that had the 2016 target date. I posted about it back in May this year on my Post 91577.
The link I linked to has since been removed, but the quote from it stating the 2016 date is in the post.
Honestly, I am a little suprised that they have maintained that 2016 date as their target date even to this day. I had thought because of their "Quiet Period" shortly after their name change that they would have pushed that date out.
