did we ever get a flood of information?

I wouldn't call it a flow, but the amount of info we've gotten recently is pretty decent. Lots of interesting stuff if you delve into it deeper. Of course some people will never be satisfied until they get a 3hr long video and 200 page long article explaining every tiny detail. And then they will complain that it's too long.

Or are they really just sitting there going "Hmm, we can't tell them all this information because it's not ready yet".

My bet is on that mainly. Yoshida was saying we will be getting stuff like videos explaining different content etc. and there's no such stuff on the horizon yet. Hopefully they will release more stuff when the game goes down to keep people more excited.

Staying so silent a few months before release just seems to shout "we have nothing really special to advertise about this game, so we hope a few cool videos of CGs will sell it"

You mean at least half a year before release.
