Yes, I remember reading about the Nimitz thing a couple of years ago. The only thing that is new with regard to that is that TTSA claims to have confirmed the validity of the FLIR camera video with the DoD.I hadn't paid attention to that link earlier but now that I read it, it really changed my view of what TTSA has actually published so far. That story from March 2015 already contains even more details and names than what TTSA has now been promoting, and is apparently written by someone who knows Fravor personally. It also mentions that the video was already leaked to YouTube years ago.
The real news I believe was the confirmation that the US government had spent some money investigating UFOs but the project was later canceled since they never produced any tangible evidence.
Elizondo haven't really said anything except that there are UFOs out there that are controlled by some intelligent entity, which sounds exciting perhaps, but if you think about it, it could just as well mean a kid with a drone (or a foreign spy plane at least).
EDIT2: He very strongly hints that he believe there are some sort of alien activity though, I would say he's being very dishonest if he later deny that, even though he tend to word things in a noncommittal way as far as I have heard.
EDIT1: Here is another source from march 2015: https://fightersweep.com/1460/x-files-edition/
